Physical origin of Davydov splitting and resonant Raman spectroscopy of Davydov components in multilayer MoTe2

Q. J. Song, Q. H. Tan, X. Zhang +6

We systematically study the high-resolution and polarized Raman spectra of multilayer (ML) MoTe2. The layer-breathing (LB) and shear (C) modes are observed in the ultralow-frequenc…
