Spin Dynamics in Bilayer Graphene and Mono- and Bilayer Transition Metal Dichalcogenides

COFFEE_KLATCH · Invited

Abstract

In this talk, I am going to present our many-body investigation on spin dynamics in bilayer graphene as well as mono- and bilayer transition metal dichalcogenides. The influence of the inter-valley scattering to the spin relaxation is addressed. The valley/spin depolarization due to the inter- and intravalley electron-hole Coulomb exchange interaction is revealed. A possible primary excitation, excimer, is proposed in bilayer WS$_2$.
