November 2017 Imaging spin dynamics in monolayer WS 2 by time-resolved Kerr rotation microscopy

Monolayer transition metal dichalcogenides (TMD) have immense potential for future spintronic and valleytronic applications due to their 2D nature and long spin/valley lifetimes. We investigate the origin of these long-lived states in n-type WS2 using time-resolved Kerr rotation microscopy and photoluminescence microscopy with ~1 μm spatial resolution… (More)
