Lower growth rates and a reduced N content, favoring graphitic sp2 structures, hinder industrial scalability due to prolonged deposition times and produce softer, less dense films with inferior hardness, elasticity, and wear resistance. Carbon nitride films deposited by magnetron sputtering exhibit growth behavior strongly influenced by plasma–surface interactions. However, nitrogen resputtering and reduced film growth rates are commonly attributed to chemical etching by positive ions. We propose an additional, unreported power-dependent mechanism involving negative ions formed at the carbon target. These ions are accelerated through the plasma sheath, reaching the substrate with high kinetic energy and inducing both chemical and physical resputtering. This effect is localized to the geometrical projection of the target, as shown by spatially resolved analysis: ellipsometry reveals thickness reduction, and x-ray photoelectron spectroscopy and Raman spectroscopy indicate nitrogen depletion within this region. Correlation between stoichiometry and structural signatures confirms the decisive role of negative ions in modifying the film composition and microstructure. At the same time, the composition of the gas mixture exerts only a minor effect.' article_number: '243301' author: - first_name: Christian full_name: Wieschhoff, Christian last_name: Wieschhoff - first_name: Chantal full_name: Theile-Rasche, Chantal last_name: Theile-Rasche - first_name: Fuzeng full_name: Wang, Fuzeng last_name: Wang - first_name: Michael full_name: Prib, Michael last_name: Prib - first_name: Viktoria Daniela Dorothea full_name: Moldt, Viktoria Daniela Dorothea last_name: Moldt - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Nieves López full_name: Salas, Nieves López last_name: Salas - first_name: Maria Teresa full_name: de los Arcos de Pedro, Maria Teresa id: '54556' last_name: de los Arcos de Pedro orcid: '0000-0002-8684-273X ' citation: ama: Wieschhoff C, Theile-Rasche C, Wang F, et al.

We introduce a paradigm shift using a many‐body plasmonic architecture inspired by statistical mechanics. By moving toward the continuum limit, local geometric variations are statistically averaged out, effectively decoupling optical performance from microscopic disorder. We implement this concept via a lithography‐ and etching‐free, multi‐step dewetting strategy, creating wafer‐scale nanoclusters. This process strategically forms a robust many‐body system by introducing numerous small satellite nanoparticles between larger particles. Crucially, this design achieves a high collective enhancement that surpasses even optimized few‐body systems, despite having larger individual gaps. Under optimized conditions, these substrates exhibit a surface‐enhanced Raman scattering enhancement factor approaching 4 × 10^8 with unprecedented reproducibility (RSD of ∼10%).

By confining the dynamics to the manifold of angular momentum coherent states, which act as the classical reference in this case, we compute the speed limit that bounds the rate of change of the state achievable without generating quantum coherence. A comparison with the unrestricted quantum speed limit enables the quantitative identification of speedups arising from polarization nonclassicality. We apply this framework to the cross-Kerr interaction, demonstrating a persistent speedup scaling as\r\n \r\n \ \r\n O\r\n \ (\r\n \r\n \ N\r\n \r\n \ )\r\n \r\n \ \r\n with the photon number\r\n \ \r\n \ N\r\n \r\n , with a parity effect in favor of even photon numbers.

Here, we demonstrate a hybrid nonlinear optoelectronic device that enhances the detection efficiency of a (001)-oriented GaAs PIN photodiode under telecommunication-wavelength illumination, where absorption is intrinsically limited to two-photon absorption (2PA). Our approach relies on the integration of a transferred, nanopatterned 385 nm-thick (111)-oriented GaAs nanofilm acting as an on-chip nonlinear frequency-conversion layer. Elliptical GaAs nanoresonators are employed to enhance second-harmonic generation (SHG) resonantly, converting incident 1550 nm radiation into above-bandgap photons efficiently absorbed by the underlying diode. Spatially resolved current–voltage measurements reveal a pronounced enhancement of the detector response in regions covered by the nanoantennas. The device exhibits a low dark current, while the metasurface-covered regions show the largest current response under 1560 nm excitation compared to the bare GaAs(100) diode and the unstructured GaAs(111) film. These results establish a direct functional link between dielectric metasurface–based nonlinear frequency conversion and electrical photodetection, providing a viable route toward integrated sub-bandgap detection schemes. article_number: '30335' article_type: original author: - first_name: Vladimir full_name: Spedt, Vladimir last_name: Spedt - first_name: Falco full_name: Meier, Falco last_name: Meier - first_name: René full_name: Geromel, René last_name: Geromel - first_name: Pascal full_name: Mahler, Pascal last_name: Mahler - first_name: Tobias full_name: Henksmeier, Tobias id: '42539' last_name: Henksmeier - first_name: Dirk full_name: Reuter, Dirk id: '37763' last_name: Reuter - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 - first_name: Cedrik full_name: Meier, Cedrik id: '20798' last_name: Meier orcid: https://orcid.org/0000-0002-3787-3572 citation: ama: Spedt V, Meier F, Geromel R, et al.

Dabei wird der Prozess der parametrischen Fluoreszenz (PDC) mithilfe von Integro-Differentialgleichungen modelliert, welche die räumliche Entwicklung der Ebene-Wellen-Operatoren beschreiben. Es wurde gezeigt, dass Supersensitivität für die Phasenempfindlichkeit dieser Interferometer erreicht werden kann, sofern die Beugung der PDC Strahlung kompensiert wird. Weiterhin führt eine Erhöhung der parametrische Verstärkung und eine Reduktion der Schmidt-Zahl zu einer Verbesserung der Phasenempfindlichkeit und einer Verkleinerung des Phasenbereiches, über den die Supersensitivität erreicht werden kann. Basierend auf der Struktur der Schmidt-Moden von SU(1,1) Interferometern wurde ein numerisches Aufbereitungsverfahren konstruiert, welches die Messung der Stärke des Squeezing und Anti-Squeezing des Zustandes ermöglicht, der durch den ersten Kristall des Interferometers erzeugt wird. Das Verfahren wurde experimentell von Kooperationspartnern angewandt, wobei eine gute Übereinstimmung mit der Theorie festgestellt wurde. Zuletzt wurden SU(1,1) Interferometer mit Laguerre-Gauß-Moden als Pump-Strahlung für die Messung von Winkelverschiebungen untersucht. Es zeigte sich, dass sich die quantenmechanisch bedingte Messunsicherheit verbessert, wenn die parametrische Verstärkung oder die Indizes der Pump-Mode erhöht werden. Das generelle Verhalten gleicht dem der Phasensensitivität. - lang: eng text: In this thesis, several aspects of high-gain multimode SU(1,1) interferometers are theoretically investigated, with the focus being on metrological applications. The parametric down-conversion (PDC) process utilized in these interferometers is theoretically described via integro-differential equations describing spatial evolution of the plane-wave operators. It is shown that for the phase sensitivity of these interferometers, supersensitivity can be reached provided that proper diffraction compensation is applied. The phase sensitivity improves if the gain is increased or if the number of effective modes is decreased. This comes at the cost of the phase-region width over which supersensitivity can be reached. Based on the Schmidt mode structure of SU(1,1) interferometers, a processing method is constructed which allows for the experimental retrieval of the levels of squeezing and anti-squeezing of the multimode state generated by the first PDC section of an SU(1,1) interferometer. It is then applied experimentally by collaborators and is found to be in good agreement with the theoretical predictions. Finally, SU(1,1) interferometers pumped with Laguerre-Gaussian beams are analyzed in the context of angular displacement measurements. As either the gain, the OAM index or the radial index of the pump are increased, the measurement uncertainty is decreased, ultimately allowing for supersensitive measurements. Generally, the behavior is the same as for the phase sensitivity. author: - first_name: Dennis full_name: Scharwald, Dennis id: '55907' last_name: Scharwald orcid: 0009-0007-5654-5412 citation: ama: Scharwald D.

We consider two interferometric configurations: firstly, the SU(1,1) interferometer where the idler incurs loss and additional dispersion in between two identical, lossless, squeezers; secondly, the induced coherence interferometer where the idler incurs loss and additional dispersion in between two identical, lossless, squeezers and where the second squeezer is seeded by the idler and a vacuum ancilla mode. Furthermore, we consider a distributed loss configuration where the idler incurs loss as it propagates in the nonlinear medium. Motivated by experimental evidence and due to the fact that broadband sources are ideal for these measurement schemes, we use the dispersive data of a third-order dispersion engineered integrated waveguide parametric down conversion (PDC) source presented in Roeder\r\n et al\r\n (2024 New J. Phys.\r\n 26\r\n \ 123025) to model the PDC spectra in the three configurations. For each configuration we consider the case of idler-only (i) absorption, (ii) additional dispersion, and (iii) the combined effects. We obtain results which outline the strength and weaknesses of the different configurations at different operation points.\r\n " article_number: '074509' author: - first_name: Martin full_name: Houde, Martin last_name: Houde - first_name: Franz full_name: Roeder, Franz id: '88149' last_name: Roeder - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn - first_name: Benjamin full_name: Brecht, Benjamin id: '27150' last_name: Brecht orcid: '0000-0003-4140-0556 ' - first_name: Nicolás full_name: Quesada, Nicolás last_name: Quesada citation: ama: Houde M, Roeder F, Silberhorn C, Brecht B, Quesada N.

These needs are—according to Ainscow’s (2007) inclusive turn—not primarily ‘special educational needs’, but diverse needs of all learners. For the rather segregated German educational system, this endeavour applies especially to primary education, where needs are still developing and pupils are not yet assigned to different types of schooling according to their needs and abilities.\r\n\r\nDespite a substantial amount of research on pupils’ basic psychological needs for autonomy, competence and social relatedness (Ryan et al., 2022), strategies that technology education teachers apply in this regard are not yet well understood. Besides interventional studies on technology education, indicating effectiveness of self‑directed and action‑oriented teaching and learning, there is a dearth of research on how teachers address different needs as a routine.\r\n\r\nThe purpose of the presented study is therefore to investigate and systematize actions and strategies teachers apply, and to specify how pupils' needs are considered when teaching technology education on a given topic.\r\n\r\nThe overall study used a mixed-methods approach to the question how pupils’ needs are characterized by themselves and by their teachers, and how they were taken into account in a lesson adapted and delivered by the teachers. In the sub-study presented here, participating primary school teachers were interviewed about their consideration of pupils’ needs whilst planning and conducting a technology education unit on the functionality of robots.\r\n\r\nThe results gained from qualitative content analysis of the interviews indicate that although the anticipation of different needs is considered challenging, teachers possess a substantiate amount of practices and strategies to take them into account.\r\n\r\nThe paper systematizes the practices teachers described in structured interviews within strategies and discusses the contribution of taking basic needs into account for inclusive technology education." alternative_title: - On Teachers’ Practices and Strategies to Teach Technology Inclusively at Primary Level author: - first_name: Franz full_name: Schröer, Franz last_name: Schröer - first_name: Claudia full_name: Tenberge, Claudia last_name: Tenberge citation: ama: 'Schröer F, Tenberge C. “They Really Need to Handle, Inspect, and Experience Things.” In: Linköping Electronic Conference Proceedings.

By immobilizing the glycopeptide antibiotic vancomycin on DONs, DON binding to Gram‐positive and Gram‐negative bacteria can be facilitated. Here, we investigate how this multivalent binding is affected by the number and arrangement of the vancomycin modifications on two‐dimensional DONs. We find that for both Gram‐positive\r\n Bacillus subtilis\r\n \ and Gram‐negative\r\n Escherichia coli\r\n , binding increases with the number of vancomycin modifications per DON. In general, binding to\r\n E. coli\r\n is stronger than to\r\n B. subtilis\r\n , which may be attributed to differences in the architectures of the cell envelopes. Interestingly, for both bacteria, the total number of vancomycin modifications appears to be more important than their arrangement, as DONs with 18 vancomycin molecules on one side show similar binding as DONs with 18 vancomycin molecules distributed over both sides. This enables the attachment of multiple probe molecules to the vancomycin‐free side of the DONs for enhancing detection efficiency without compromising binding affinity. These results may thus provide guidelines for the design and synthesis of vancomycin‐modified DONs for antimicrobial drug delivery and pathogen detection.\r\n " article_number: e70436 author: - first_name: Özge full_name: Coşkuner Leineweber, Özge last_name: Coşkuner Leineweber - first_name: Ulrike full_name: Hofmann, Ulrike last_name: Hofmann - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier - first_name: Yixin full_name: Zhang, Yixin last_name: Zhang - first_name: Adrian Clemens full_name: Keller, Adrian Clemens id: '48864' last_name: Keller orcid: 0000-0001-7139-3110 citation: ama: Coşkuner Leineweber Ö, Hofmann U, Grundmeier G, Zhang Y, Keller AC.

In fact, its operation, combined with single qubit rotations allows to realise any quantum circuit. Several strategies have been adopted in order to build quantum gates. Among them, photonics offers the dual advantage of excellent isolation from the environment and ease of manipulation at the single qubit level. Here we adopt a scalable time-multiplexed approach in order to build a fully reconfigurable architecture capable of implementing a post-selected C-NOT gate with a fidelity of (93.8 ± 1.4)%. We then show how our time-multiplexed platform can be employed to combine a C-NOT and a single qubit gate in order to generate the four Bell states. article_number: '5683' article_type: original author: - first_name: Federico full_name: Pegoraro, Federico id: '88928' last_name: Pegoraro - first_name: Philip full_name: Held, Philip id: '68236' last_name: Held - first_name: Jonas full_name: Lammers, Jonas last_name: Lammers - first_name: Benjamin full_name: Brecht, Benjamin id: '27150' last_name: Brecht orcid: '0000-0003-4140-0556 ' - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn citation: ama: Pegoraro F, Held P, Lammers J, Brecht B, Silberhorn C.
