- ItemWebinar SCOAP³(Hannover : Technische Informationsbibliothek, 2018) Ludwig, JudithIm diesem SCOAP³-Webinar, welches am 07. Juni 2018 stattgefunden hat, wurden die Grundlagen von SCOAP³ und SCOAP³-DH vorgestellt. SCOAP³ steht für „Sponsoring Consortium for Open Access Publishing in Particle Physics“ und ist ein internationales Konsortium unter Führung des des CERN zur Förderung von Open Access im Bereich der Hochenergiephysik (HEP). SCOAP³-DH steht für Sponsoring Consortium for Open Access Publishing in Particle Physics - Deutsche Hochschulen. SCOAP³-DH hat als nationale Kontaktstelle die Aufgabe, die finanzielle Beteiligung der deutschen Hochschulen an dem internationalen Konsortium SCOAP³ zu organisieren.

- ItemAluminum-Doped Zinc Oxide Improved by Silver Nanowires for Flexible, Semitransparent and Conductive Electrodes on Textile with High Temperature Stability(Basel : MDPI, 2023) Hupfer, Maximilian Lutz; Gawlik, Annett; Dellith, Jan; Plentz, JonathanIn order to facilitate the design freedom for the implementation of textile-integrated electronics, we seek flexible transparent conductive electrodes (TCEs) that can withstand not only the mechanical stresses encountered during use but also the thermal stresses of post-treatment. The transparent conductive oxides (TCO) typically used for this purpose are rigid in comparison to the fibers or textiles they are intended to coat. In this paper, a TCO, specifically aluminum-doped zinc oxide (Al:ZnO), is combined with an underlying layer of silver nanowires (Ag-NW). This combination brings together the advantages of a closed, conductive Al:ZnO layer and a flexible Ag-NW layer, forming a TCE. The result is a transparency of 20–25% (within the 400–800 nm range) and a sheet resistance of 10 Ω/sq that remains almost unchanged, even after post-treatment at 180 °C.
- ItemAmorphous Silicon Thin-Film Solar Cells on Fabrics as Large-Scale Detectors for Textile Personal Protective Equipment in Active Laser Safety †(Basel : MDPI, 2023) Gawlik, Annett; Brückner, Uwe; Schmidl, Gabriele; Wagner, Volker; Paa, Wolfgang; Plentz, JonathanLaser safety is starting to play an increasingly important role, especially when the laser is used as a tool. Passive laser safety systems quickly reach their limits and, in some cases, provide inadequate protection. To counteract this, various active systems have been developed. Flexible and especially textile-protective materials pose a special challenge. The market still lacks personal protective equipment (PPE) for active laser safety. Covering these materials with solar cells as large-area optical detectors offers a promising possibility. In this work, an active laser protection fabric with amorphous silicon solar cells is presented as a large-scale sensor for continuous wave and pulsed lasers (down to ns). First, the fabric and the solar cells were examined separately for irradiation behavior and damage. Laser irradiation was performed at wavelengths of 245, 355, 532, and 808 nm. The solar cell sensors were then applied directly to the laser protection fabric. The damage and destruction behavior of the active laser protection system was investigated. The results show that the basic safety function of the solar cell is still preserved when the locally damaged or destroyed area is irradiated again. A simple automatic shutdown system was used to demonstrate active laser protection within 50 ms.
- ItemThe double-well Bose Hubbard model with nearest-neighbor and cavity-mediated long-range interactions([Ithaca, NY] : Arxiv.org, 2023) Sicks, Johannes; Rieger, HeikoWe consider a one-dimensional Bose-Hubbard model (BHM) with on-site double-well potentials and study the effect of nearest-neighbor repulsion and cavity-mediated long-range interactions by calculating the ground-state phase diagrams with quantum Monte-Carlo simulations. We show that when the intra-well repulsion is as strong as the on-site repulsion a dimerized Mott insulator phase appears at the tip of the dimerized Density Wave phase for a density of one particle per double well. Furthermore, we find a dimerized Haldane insulator phase in the double-well BHM with nearest-neighbor interaction, which is identical to a dimerized BHM with repulsive interactions up to the third neighbor.
