Bandgap Renormalization and Trap-Induced Absorption in MoWS2 Single-Crystal

Pravrati Taank and K. V. Adarsh

Not Accessible

Your library or personal account may give you access

Abstract

We studied many-body dynamics in MoWS2 single-crystal using time and energy-resolved reflection spectroscopy. We detected ultrafast bandgap renormalization, overwhelmed by trap-induced absorption (TIA) at longer timescale. Furthermore, non-decaying TIA caused formation of long-lived trapped exciton.
