High-temperature observation of intralayer, interlayer, and Rydberg excitons in bulk van der Waals alloy single crystals
Pravrati Taank, Asif Ali, Aravind Raji +4
Transition metal dichalcogenides (TMDs) exhibit remarkable optical properties due to the diverse number of strongly bound excitons, which can be fine-tuned by alloying. Despite a f…

Evidence of Hot Carrier Extraction in Metal Halide Perovskite Solar Cells
S. Sourabh, H. Afshari, V. R. Whiteside +9
The presence of hot carriers is presented in the operational properties of an (FA,Cs)Pb(I, Br, Cl)3 solar cell at ambient temperatures and under practical solar concentration. At 1…

Tunable Magnon-Photon Coupling by Magnon Band Gap in a Layered Hybrid Perovskite Antiferromagnet
Yi Li, Timothy Draher, Andrew H. Comstock +17
Tunability of coherent coupling between fundamental excitations is an important prerequisite for expanding their functionality in hybrid quantum systems. In hybrid magnonics, the d…
