Monolayer dichalcogenides and their heterostructures: optospintronics, electronic properties, valley dynamics


Abstract

We study the optical and electronic properties of monolayer transition metal dichalcogenides and a variety of heterostructures consisting of different two-dimensional materials in a joint project combining time-resolved optical spectroscopy and theory. The aim is to investigate spin and valley polarization dynamics in monolayers, tunneling of polarized carriers between individual layers of a heterostructure, as well as the properties of interlayer excitons in heterostructures. We will vary the interlayer distance and relative crystallographic orientation of adjacent layers to control the valley dynamics and interlayer exciton energies in our heterostructures.
