--- _id: '64864' abstract: - lang: eng text: Probing novel properties, arising from twisted interfaces, has traditionally relied on the stacking of exfoliated two-dimensional materials and the spontaneous formation of van der Waals bonds. So far, investigations involving intimate covalent or ionic bonds have not been a focus. Yet, we show here that an established technique, involving thermocompressional wafer bonding, works well for creating twisted non-van der Waals interfaces. We have successfully bonded z-cut lithium niobate single crystals to create ferroelectric oxide interfaces with strong polar discontinuities and have mapped the associated emergent interfacial conductivity. In some instances, a dramatic change in microstructure occurs, involving local dipolar switching. A twist-induced collapse in the capability of the system to effec8tively screen interfacial bound charge is implied. Importantly, this only occurs around specific moiré twist angles with sparse coincident lattices and associated short-range aperiodicity. In quasicrystals, aperiodicity is known to induce pseudo-bandgaps and we suspect a similar phenomenon here. article_number: '1842' article_type: original author: - first_name: Andrew full_name: Rogers, Andrew last_name: Rogers - first_name: Kristina full_name: Holsgrove, Kristina last_name: Holsgrove - first_name: Nils A. full_name: Schäfer, Nils A. last_name: Schäfer - first_name: Boris full_name: Koppitz, Boris last_name: Koppitz - first_name: Conor J. full_name: McCluskey, Conor J. last_name: McCluskey - first_name: Shivani full_name: Yedama, Shivani last_name: Yedama - first_name: Ronan full_name: Lynch, Ronan last_name: Lynch - first_name: Keelan full_name: Sloan, Keelan last_name: Sloan - first_name: Barry full_name: Porter, Barry last_name: Porter - first_name: Adam full_name: Sykes, Adam last_name: Sykes - first_name: Alex full_name: Catalan Daniels, Alex last_name: Catalan Daniels - first_name: Romualdo S. full_name: Silva, Romualdo S. last_name: Silva - first_name: Flavio Y. full_name: Bruno, Flavio Y. last_name: Bruno - first_name: Sam D. full_name: Seddon, Sam D. last_name: Seddon - first_name: Haidong full_name: Lu, Haidong last_name: Lu - first_name: Michael full_name: Rüsing, Michael id: '22501' last_name: Rüsing orcid: 0000-0003-4682-4577 - first_name: Christa full_name: Fink, Christa last_name: Fink - first_name: Philipp full_name: Fahler-Muenzer, Philipp last_name: Fahler-Muenzer - first_name: Sarah full_name: Fearn, Sarah last_name: Fearn - first_name: Sandrine E.

Despite its fundamental importance, precisely defining atomic and molecular surfaces has long been a puzzle. Among the available definitions, a straightforward and elegant approach by Bader describes a molecular surface as an iso-density surface beyond which the electron density drops below a certain cut-off. However, so far neither this theory nor a decisive value for the density cut-off have been amenable to experimental verification due to the limitations of conventional experimental methods. In the present study, we employ a state-of-the-art experimental method based on the recently developed concept of thermodynamically effective (TE) surfaces to tackle this longstanding problem. By studying a set of 104 molecules, a close to perfect agreement between quantum chemical evaluations of iso-density surfaces contoured at a cut-off density of 0.0016 a.u. and experimental results obtained via thermodynamic phase change data is demonstrated, with a mean unsigned percentage deviation of 1.6% and a correlation coefficient of 0.995. Accordingly, we suggest the iso-density surface contoured at an electron density value of 0.0016 a.u. as a representation of the surface of atoms and molecules. article_number: '6086' author: - first_name: Amin full_name: Alibakhshi, Amin last_name: Alibakhshi - first_name: Lars V. full_name: Schäfer, Lars V. last_name: Schäfer citation: ama: Alibakhshi A, Schäfer LV.

PVVBs are typically generated through the superposition of perfect vortex beams, which suffer from the limited number of topological charges (TCs). Furthermore, dynamic control of PVVBs is desirable and has not been reported. We propose and experimentally demonstrate hybrid grafted perfect vector vortex beams (GPVVBs) and their dynamic control. Hybrid GPVVBs are generated through the superposition of grafted perfect vortex beams with a multifunctional metasurface. The generated hybrid GPVVBs possess spatially variant rates of polarization change due to the involvement of more TCs. Each hybrid GPVVB includes different GPVVBs in the same beam, adding more design flexibility. Moreover, these beams are dynamically controlled with a rotating half waveplate. The generated dynamic GPVVBs may find applications in the fields where dynamic control is in high demand, including optical encryption, dense data communication, and multiple particle manipulation. article_number: '3915' author: - first_name: Hammad full_name: Ahmed, Hammad last_name: Ahmed - first_name: Muhammad Afnan full_name: Ansari, Muhammad Afnan last_name: Ansari - first_name: Yan full_name: Li, Yan last_name: Li - first_name: Thomas full_name: Zentgraf, Thomas id: '30525' last_name: Zentgraf orcid: 0000-0002-8662-1101 - first_name: Muhammad Qasim full_name: Mehmood, Muhammad Qasim last_name: Mehmood - first_name: Xianzhong full_name: Chen, Xianzhong last_name: Chen citation: ama: Ahmed H, Ansari MA, Li Y, Zentgraf T, Mehmood MQ, Chen X.

Indeed, optical resonators such as microcavities and plasmonic antennas offer excellent control but only over a limited spectral range. Strategies to mutually tune and match emission and resonator frequency are often required, which is intricate and precludes the possibility of enhancing multiple transitions simultaneously. In this letter, we report a strong radiative emission rate enhancement of Er3+-ions across the telecommunications C-band in a single plasmonic waveguide based on the Purcell effect. Our gap waveguide uses a reverse nanofocusing approach to efficiently enhance, extract and guide emission from the nanoscale to a photonic waveguide while keeping plasmonic losses at a minimum. Remarkably, the large and broadband Purcell enhancement allows us to resolve Stark-split electric dipole transitions, which are typically only observed under cryogenic conditions. Simultaneous radiative emission enhancement of multiple quantum states is of great interest for photonic quantum networks and on-chip data communications. article_number: '2719' author: - first_name: Nicholas Alexander full_name: Güsken, Nicholas Alexander id: '112030' last_name: Güsken orcid: 0000-0002-4816-0666 - first_name: Ming full_name: Fu, Ming last_name: Fu - first_name: Maximilian full_name: Zapf, Maximilian last_name: Zapf - first_name: Michael P. full_name: Nielsen, Michael P. last_name: Nielsen - first_name: Paul full_name: Dichtl, Paul last_name: Dichtl - first_name: Robert full_name: Röder, Robert last_name: Röder - first_name: Alex S. full_name: Clark, Alex S. last_name: Clark - first_name: Stefan A. full_name: Maier, Stefan A. last_name: Maier - first_name: Carsten full_name: Ronning, Carsten last_name: Ronning - first_name: Rupert F. full_name: Oulton, Rupert F. last_name: Oulton citation: ama: Güsken NA, Fu M, Zapf M, et al.

Optimising the performance of electrocatalysts requires atomic-scale information, but it is difficult to obtain. Here, we use atom probe tomography to elucidate the 3D structure of 10 nm sized Co2FeO4 and CoFe2O4 nanoparticles during oxygen evolution reaction (OER). We reveal nanoscale spinodal decomposition in pristine Co2FeO4. The interfaces of Co-rich and Fe-rich nanodomains of Co2FeO4 become trapping sites for hydroxyl groups, contributing to a higher OER activity compared to that of CoFe2O4. However, the activity of Co2FeO4 drops considerably due to concurrent irreversible transformation towards CoIVO2 and pronounced Fe dissolution. In contrast, there is negligible elemental redistribution for CoFe2O4 after OER, except for surface structural transformation towards (FeIII, CoIII)2O3. Overall, our study provides a unique 3D compositional distribution of mixed Co-Fe spinel oxides, which gives atomic-scale insights into active sites and the deactivation of electrocatalysts during OER. article_number: '179' article_type: original author: - first_name: Weikai full_name: Xiang, Weikai last_name: Xiang - first_name: Nating full_name: Yang, Nating last_name: Yang - first_name: Xiaopeng full_name: Li, Xiaopeng last_name: Li - first_name: Julia full_name: Linnemann, Julia id: '116779' last_name: Linnemann orcid: 0000-0001-6883-5424 - first_name: Ulrich full_name: Hagemann, Ulrich last_name: Hagemann - first_name: Olaf full_name: Ruediger, Olaf last_name: Ruediger - first_name: Markus full_name: Heidelmann, Markus last_name: Heidelmann - first_name: Tobias full_name: Falk, Tobias last_name: Falk - first_name: Matteo full_name: Aramini, Matteo last_name: Aramini - first_name: Serena full_name: DeBeer, Serena last_name: DeBeer - first_name: Martin full_name: Muhler, Martin last_name: Muhler - first_name: Kristina full_name: Tschulik, Kristina last_name: Tschulik - first_name: Tong full_name: Li, Tong last_name: Li citation: ama: Xiang W, Yang N, Li X, et al. 3D atomic-scale imaging of mixed Co-Fe spinel oxide nanoparticles during oxygen evolution reaction.

In this work, we demonstrate that polycrystalline MAPbI3s undergo drastic changes in optical properties at moderate field strengths with an ultrafast response time, via transient Wannier Stark localization. The distinct band structure of this material - the large lattice periodicity, the narrow electronic energy bandwidths, and the coincidence of these two along the same high-symmetry direction – enables relatively weak fields to bring this material into the Wannier Stark regime. Its polycrystalline nature is not detrimental to the optical switching performance of the material, since the least dispersive direction of the band structure dominates the contribution to the optical response, which favors low-cost fabrication. Together with the outstanding photophysical properties of MAPbI3, this finding highlights the great potential of this material in ultrafast light modulation and novel photonic applications. article_number: '5719' author: - first_name: Daniel full_name: Berghoff, Daniel id: '38175' last_name: Berghoff - first_name: Johannes full_name: Bühler, Johannes last_name: Bühler - first_name: Mischa full_name: Bonn, Mischa last_name: Bonn - first_name: Alfred full_name: Leitenstorfer, Alfred last_name: Leitenstorfer - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: Heejae full_name: Kim, Heejae last_name: Kim citation: ama: Berghoff D, Bühler J, Bonn M, Leitenstorfer A, Meier T, Kim H.

Electrolyte alkali metal cations have been shown to modify the activity and reaction intermediates, however, the exact mechanism is at question due to unexplained deviations from the cation size trend. Our X-ray absorption spectroelectrochemical results show that bigger cations shift the Ni2+/(3+δ)+ redox peak and OER activity to lower potentials (however, with typical discrepancies), following the order CsOH > NaOH ≈ KOH > RbOH > LiOH. Here, we find that the OER activity follows the variations in electrolyte pH rather than a specific cation, which accounts for differences both in basicity of the alkali hydroxides and other contributing anomalies. Our density functional theory-derived reactivity descriptors confirm that cations impose negligible effect on the Lewis acidity of Ni, Fe, and O lattice sites, thus strengthening the conclusions of an indirect pH effect. article_number: '6181' author: - first_name: Mikaela full_name: Görlin, Mikaela last_name: Görlin - first_name: Joakim full_name: Halldin Stenlid, Joakim last_name: Halldin Stenlid - first_name: Sergey full_name: Koroidov, Sergey last_name: Koroidov - first_name: Hsin-Yi full_name: Wang, Hsin-Yi last_name: Wang - first_name: Mia full_name: Börner, Mia last_name: Börner - first_name: Mikhail full_name: Shipilin, Mikhail last_name: Shipilin - first_name: Aleksandr full_name: Kalinko, Aleksandr last_name: Kalinko - first_name: Vadim full_name: Murzin, Vadim last_name: Murzin - first_name: Olga V. full_name: Safonova, Olga V. last_name: Safonova - first_name: Maarten full_name: Nachtegaal, Maarten last_name: Nachtegaal - first_name: Abdusalam full_name: Uheida, Abdusalam last_name: Uheida - first_name: Joydeep full_name: Dutta, Joydeep last_name: Dutta - first_name: Matthias full_name: Bauer, Matthias id: '47241' last_name: Bauer orcid: 0000-0002-9294-6076 - first_name: Anders full_name: Nilsson, Anders last_name: Nilsson - first_name: Oscar full_name: Diaz-Morales, Oscar last_name: Diaz-Morales citation: ama: Görlin M, Halldin Stenlid J, Koroidov S, et al.

The photoresponse of graphene junctions is characterized by two competing photocurrent generation mechanisms: a conventional photovoltaic effect and a more dominant hot-carrier-assisted photothermoelectric (PTE) effect. The PTE effect is understood to rely on variations in the Seebeck coefficient through the graphene doping profile. A second PTE effect can occur across a homogeneous graphene channel in the presence of an electronic temperature gradient. Here, we study the latter effect facilitated by strongly localised plasmonic heating of graphene carriers in the presence of nanostructured electrical contacts resulting in electronic temperatures of the order of 2000 K. At certain conditions, the plasmon-induced PTE photocurrent contribution can be isolated. In this regime, the device effectively operates as a sensitive electronic thermometer and as such represents an enabling technology for development of hot carrier based plasmonic devices.' article_number: '5190' author: - first_name: Viktoryia full_name: Shautsova, Viktoryia last_name: Shautsova - first_name: Themistoklis full_name: Sidiropoulos, Themistoklis last_name: Sidiropoulos - first_name: Xiaofei full_name: Xiao, Xiaofei last_name: Xiao - first_name: Nicholas A. full_name: Güsken, Nicholas A. last_name: Güsken - first_name: Nicola C.

When looking at its quantum properties, described by photon correlations, new information about the state of the matter generating the radiation can be revealed. In particular the difference between independent and entangled emitters, which is at the heart of quantum mechanics, can be made visible in the photon statistics of the emitted light. The well-studied phenomenon of superradiance occurs when quantum–mechanical correlations between the emitters are present. Notwithstanding, superradiance was previously demonstrated only in terms of classical light properties. Here, we provide the missing link between quantum correlations of the active material and photon correlations in the emitted radiation. We use the superradiance of quantum dots in a cavity-quantum electrodynamics laser to show a direct connection between superradiant pulse emission and distinctive changes in the photon correlation function. This directly demonstrates the importance of quantum–mechanical correlations and their transfer between carriers and photons in novel optoelectronic devices. article_type: original author: - first_name: Frank full_name: Jahnke, Frank last_name: Jahnke - first_name: Christopher full_name: Gies, Christopher last_name: Gies - first_name: Marc full_name: Aßmann, Marc last_name: Aßmann - first_name: Manfred full_name: Bayer, Manfred last_name: Bayer - first_name: H.
