Strain-Induced Activation of Symmetry-Forbidden Exciton-Phonon Couplings for Enhanced Phonon-Assisted Photoluminescence in MoS Monolayers
Rishabh Saraswat, Rekha Verma, Sitangshu Bhattacharya
Phonon-assisted photoluminescence (PL) in molybdenum-based two-dimensional dichalcogenides is typically weak due to the dormant phonon coupling with optically inactive momentum-dar…

Phonon Assisted Exciton Processes in Two-Dimensional Tungsten Monocarbide
Rishabh Saraswat, Miroslav Kolos, Rekha Verma +2
n this study, we utilize a rigorous ab initio-based finite momentum Bethe-Salpeter equation to investigate the photoluminescence emission in two-dimensional hexagonal tungsten carb…
