Raman scattering in transition metal dichalcogenides (B06)

• Subject Area: Experimental Condensed Matter Physics
• Term: from 2017 to 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 314695032

The relativistic spin-orbit interaction can be particularly strong in transition metal dichalcogenides (TMDCs), like MoS2, MoSe2, WS2 and WSe2, which leads to large intrinsic spin splittings of the electron-ic bands in these layered structures. Electronic excitations, like plasmons or spin-density waves, have not yet been observed in these materials. In this project, the aim is to observe and systematically inves-tigate low-energy excitations like plasmons and spin-density waves in TMDCs by resonant Raman scat-tering.
