Here, we present a versatile template-assisted synthesis of nanostructured tin dioxide thin films using cellulose nanocrystals (CNCs). We demonstrate that the structural features of CNC-templated tin dioxide films strongly depend on the precursor composition. The precursor properties were studied by using low-temperature nuclear magnetic resonance spectroscopy of tin tetrachloride in solution. We demonstrate that it is possible to optimize the precursor conditions to obtain homogeneous precursor mixtures and therefore highly porous thin films with pore dimensions in the range of 10–20 nm (ABET = 46–64 m2 g–1, measured on powder). Finally, by exploiting the high surface area of the material, we developed a resistive gas sensor based on CNC-templated tin dioxide. The sensor shows high sensitivity to carbon monoxide (CO) in ppm concentrations and low cross-sensitivity to humidity. Most importantly, the sensing kinetics are remarkably fast; both the response to the analyte gas and the signal decay after gas exposure occur within a few seconds, faster than in standard SnO2-based CO sensors. This is attributed to the high gas accessibility of the very thin porous film."}],"quality_controlled":"1","citation":{"apa":"Ivanova, A., Frka-Petesic, B., Paul, A., Wagner, T., Jumabekov, A.

Hydrogel micropatterns are fabricated by spreading the prepolymer mixture on the substrate, followed by UV photopolymerization through a micropatterned mask. The hydrogel is covalently bonded to the substrate surface. Al2O3 is produced by swelling the hydrogel in a saturated aluminum nitrate solution and subsequent thermal conversion/calcination. As a result, micropatterned porous Al2O3 microdots with heights in µm range and large specific surface areas up to 274 m2 g−1 are obtained.

To achieve highly ordered inverse opal structures, one important issue during the colloidal crystal templating procedure is to form a stable precursor network before the template loses its structural integrity at high temperature. Using poly(methyl methacrylate), PMMA, colloidal crystal templates, it is essential to consider the physical and chemical changes of the precursors induced by the changes of PMMA during the thermal conversion. For a systematic investigation of this matter, we synthesized a variety of metal oxide inverse opals from the respective metal nitrates, including Cr2O3, Ga2O3, Fe2O3, In2O3, CuO, CeO2, and ZnO, to compare the effect of various modifications of precursors on the structural and optical properties.

A commonly used approach to describe theoretical properties includes a phenomenological single-mode equation that complements the equation for the nonlinear optical response (interband polarization) of the semiconductor. Here, we show how to replace the single-mode equation by a fully predictive transfer function method that, in contrast to the single-mode equation, accounts for propagation, retardation, and pulse-filtering effects of the incident light field traversing the distributed Bragg reflector (DBR) mirrors, without substantially increasing the numerical complexity of the solution. As examples, we use cavities containing GaAs quantum wells and transition-metal dichalcogenides (TMDs).</jats:p>","lang":"eng"}],"article_number":"G112","language":[{"iso":"eng"}],"doi":"10.1364/ao.392014","year":"2020","title":"Transfer function replacement of phenomenological single-mode equations in semiconductor microcavity modeling","author":[{"first_name":"M.","last_name":"Carcamo","full_name":"Carcamo, M."},{"id":"27271","full_name":"Schumacher, Stefan","first_name":"Stefan","orcid":"0000-0003-4042-4951","last_name":"Schumacher"},{"full_name":"Binder, R.","last_name":"Binder","first_name":"R."}],"publication_identifier":{"issn":["1559-128X","2155-3165"]},"publication_status":"published","date_updated":"2023-04-20T15:42:52Z","intvolume":"        59"},{"_id":"40444","publisher":"American Physical Society (APS)","volume":101,"user_id":"16199","status":"public","citation":{"bibtex":"@article{von Bardeleben_Rauls_Gerstmann_2020, title={Carbon vacancy-related centers in &#60;mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\"&#62;&#60;mml:mn&#62;3&#60;/mml:mn&#62;&#60;mml:mi&#62;C&#60;/mml:mi&#62;&#60;/mml:math&#62;-silicon carbide: Negative-&#60;mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\"&#62;&#60;mml:mi&#62;U&#60;/mml:mi&#62;&#60;/mml:math&#62; properties and structural transformation}, volume={101}, DOI={<a href=\"https://doi.org/10.1103/physrevb.101.184108\">10.1103/physrevb.101.184108</a>}, number={18184108}, journal={Physical Review B}, publisher={American Physical Society (APS)}, author={von Bardeleben, H.

This holds in particular for the energy and the spatial localization of the highest occupied and lowest unoccupied molecular orbitals. In addition to a substantial gap narrowing, a pronounced separation of photoexcited electrons and holes is predicted in some instances.

In inhomogeneous ensembles a macroscopic optical polarization decays rapidly due to dephasing, which, however, is reversible in photon echoes carrying complete information about the coherent ensemble dynamics. Control of the echo emission time is mandatory for applications. Here, we propose a concept to reach this goal. In a two-pulse photon echo sequence, we apply an additional resonant control pulse with multiple of 2<jats:italic>π</jats:italic> area. Depending on its arrival time, the control slows down dephasing or rephasing of the exciton ensemble during its action. We demonstrate for self-assembled (In,Ga)As quantum dots that the photon echo emission time can be retarded or advanced by up to 5 ps relative to its nominal appearance time without control. This versatile protocol may be used to obtain significantly longer temporal shifts for suitably tailored control pulses.</jats:p>"}],"issue":"1","publication":"Communications Physics","user_id":"16199","volume":3,"_id":"20773","status":"public","project":[{"_id":"53","name":"TRR 142"},{"name":"TRR 142 - Project Area A","_id":"54"},{"name":"TRR 142 - Subproject A2","_id":"59"}],"citation":{"mla":"Kosarev, Alexander N., et al. “Accurate Photon Echo Timing by Optical Freezing of Exciton Dephasing and Rephasing in Quantum Dots.” <i>Communications Physics</i>, vol. 3, no. 1, 228, 2020, doi:<a href=\"https://doi.org/10.1038/s42005-020-00491-2\">10.1038/s42005-020-00491-2</a>.","bibtex":"@article{Kosarev_Rose_Poltavtsev_Reichelt_Schneider_Kamp_Höfling_Bayer_Meier_Akimov_2020, title={Accurate photon echo timing by optical freezing of exciton dephasing and rephasing in quantum dots}, volume={3}, DOI={<a href=\"https://doi.org/10.1038/s42005-020-00491-2\">10.1038/s42005-020-00491-2</a>}, number={1228}, journal={Communications Physics}, author={Kosarev, Alexander N. and Rose, Hendrik and Poltavtsev, Sergey V. and Reichelt, Matthias and Schneider, Christian and Kamp, Martin and Höfling, Sven and Bayer, Manfred and Meier, Torsten and Akimov, Ilya A.}, year={2020} }","ama":"Kosarev AN, Rose H, Poltavtsev SV, et al.

With their additional degree of freedom, the vorticity, they have been widely investigated in many physical systems and different materials for fundamental interest and for applications in data storage and information processing. Vortices have also been observed in non-equilibrium exciton-polariton condensates in planar semiconductor microcavities. There they appear spontaneously or can be created and pinned in space using ring-shaped optical excitation profiles. However, using the vortex state for information processing not only requires creation of a vortex but also efficient control over the vortex after its creation. Here we demonstrate a simple approach to control and switch a localized polariton vortex between opposite states. In our scheme, both the optical control of vorticity and its detection through the orbital angular momentum of the emitted light are implemented in a robust and practical manner."}],"issue":"1","publication":"Nature communications","doi":"10.1038/s41467-020-14702-5","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://www.nature.com/articles/s41467-020-14702-5","open_access":"1"}],"intvolume":"        11","date_updated":"2023-04-21T11:23:46Z","publication_status":"published","author":[{"first_name":"Torsten","orcid":"0000-0001-8864-2072","last_name":"Meier","full_name":"Meier, Torsten","id":"344"},{"full_name":"Ma, Xuekai","first_name":"Xuekai","last_name":"Ma"},{"first_name":"Bernd","last_name":"Berger","full_name":"Berger, Bernd"},{"full_name":"Aßmann, Marc","last_name":"Aßmann","first_name":"Marc"},{"full_name":"Driben, Rodislav","first_name":"Rodislav","last_name":"Driben"},{"full_name":"Schneider, Christian","first_name":"Christian","last_name":"Schneider"},{"first_name":"Sven","last_name":"Höfling","full_name":"Höfling, Sven"},{"id":"27271","full_name":"Schumacher, Stefan","last_name":"Schumacher","orcid":"0000-0003-4042-4951","first_name":"Stefan"}],"year":"2020","title":"Realization of all-optical vortex switching in exciton-polariton condensates"},{"date_created":"2020-12-16T14:23:16Z","type":"conference","department":[{"_id":"15"},{"_id":"170"},{"_id":"293"},{"_id":"230"},{"_id":"429"},{"_id":"35"}],"publication":"Ultrafast Phenomena and Nanophotonics XXIV","series_title":"SPIE Proceedings","language":[{"iso":"eng"}],"doi":"10.1117/12.2545924","title":"k.p-based multiband simulations of non-degenerate two-photon absorption in bulk GaAs","year":"2020","publication_identifier":{"isbn":["9781510633193","9781510633209"]},"author":[{"full_name":"Hannes, Wolf-Rüdiger","orcid":"https://orcid.org/0000-0003-1210-4838","first_name":"Wolf-Rüdiger","last_name":"Hannes","id":"66789"},{"id":"344","full_name":"Meier, Torsten","first_name":"Torsten","orcid":"0000-0001-8864-2072","last_name":"Meier"}],"publication_status":"published","date_updated":"2023-04-21T11:22:44Z","intvolume":"     11278","citation":{"mla":"Hannes, Wolf-Rüdiger, and Torsten Meier. “K.p-Based Multiband Simulations of Non-Degenerate Two-Photon Absorption in Bulk GaAs.” <i>Ultrafast Phenomena and Nanophotonics XXIV</i>, edited by Markus Betz and Abdulhakem Y.
