Abstract

The project is focused on the spin-valley physics in transition-metal dichalcogenide monolayers and heterostructures, studied over a broad energy range, from excitonic quasiparticles at optical frequencies to low-energy electronic and vibronic excitations. The interplay between spatial propagation of excitons and their spin-valley polarization degree of freedom will be studied via time- and spatially resolved photoluminescence experiments, while low-frequency Raman scattering will be applied for the investigation of the twist-angle dependence of interlayer vibrations.
