Spin-valley dynamics in monolayer semiconductors and their heterostructures: Optical transport and low-frequency Raman spectroscopy (B05)

• Subject Area: Experimental Condensed Matter Physics ; Theoretical Condensed Matter Physics
• Term: since 2017
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 314695032

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.
