Electronic Structure Dynamics in Semimetallic TMD Mo<sub>1-x</sub>W<sub>x</sub>Te<sub>2</sub> using Time- and Angle-Resolved Photoemission Spectroscopy

ORAL

Abstract

In time- and angle-resolved photoemission spectroscopy (trARPES), direct measurements can be made of both the electronic structure dynamics, and the dynamics of interaction between electronic and structural degrees of freedom in a material. Here we discuss trARPES experiments on the semimetallic transition metal dichalcogenide Mo1-xWxTe2 and examine the dynamics of the topological surface states in these materials. The relationship between the dynamics of these electronic features and the material's structural features will be discussed.
