Exciton-Selective Phonon Coupling in a Lead Halide Perovskite
Pradeepa H. L., Sagnik Chatterjee, Sayantan Patra +6
Exciton-phonon interactions govern the optical response of semiconductors, yet disentangling multiple coupling channels in lead halide perovskites remains challenging. We investiga…
Effects of Reduced Interlayer Interactions on the K-point Excitons of MoS Nanoscrolls
Sagnik Chatterjee, Tamaghna Chowdhury, Pablo Díaz Núñez +6
Transition metal dichalcogenide (TMD) nanoscrolls (NS) exhibit significant photoluminescence (PL) signals despite their multilayer structure, which cannot be explained by the strai…
Tensile strain induced brightening of momentum forbidden dark exciton in WS
Tamaghna Chowdhury, Sagnik Chatterjee, Dibyasankar Das +8
Transition-metal dichalcogenides (TMDs) host tightly bound quasi-particles called excitons. Based on spin and momentum selection rules, these excitons can be either optically brigh…
