Accelerated development of amorphous InZnO thin films as transparent conductive Cu diffusion barriers
Stefanie Frick, Reyu Sakakibara, Manuel Kober-Czerny +4
In light of the increasing supply chain concerns regarding silver for solar cell metallization, the replacement of the silver contacts by copper is desirable. As copper diffuses re…
Physics-informed time-series forecasting of perovskite photoluminescence stability
Alexander Wieczorek, Manuel Kober-Czerny, Fábio Lopes +5
Accelerated ageing using elevated temperatures and illumination is one of the most common methods to rapidly study the stability of novel semiconductor materials. However, as the p…
Boron Co-Alloying in AlScN Wurtzite Ferroelectrics: Insights from an 850-Sample Combinatorial Study
Federica Messi, Nathan Rodkey, Manuel Kober-Czerny +1
AlScN wurtzite ferroelectrics are promising candidates for energy-efficient non-volatile memory. However, AlScN suffers from a high coercive field and reduced cycling endurance, an…
Radiation-Triggered Superfluorescent Scintillation in Quantum-Ordered Perovskite Nanocrystal Superlattices
Matteo L. Zaffalon, Andrea Fratelli, Taras Sekh +8
Superfluorescence, a cooperative emission phenomenon arising from the coherent coupling of excited dipoles, has historically been observed under optical excitation in carefully eng…
Accelerating the development of oxynitride thin films: A combinatorial investigation of the Al-Si-O-N system
Stefanie Frick, Oleksandr Pshyk, Arnold Müller +3
Oxynitrides are used in a variety of applications including photocatalysts, high-k dielectrics or wear-resistant coatings and often show intriguing multi-functionality. To accelera…
Ultrafast Superradiant Scintillation from Weakly Confined CsPbBr3 Nanocrystals
Matteo L. Zaffalon, Andrea Fratelli, Zhanzhao Li +7
Efficiency and emission rate are two traditionally conflicting parameters in radiation detection, and achieving their simultaneous maximization could significantly advance ultrafas…
