Anisotropic phonon dispersion and optoelectronic properties of a few layers HfS2
Journal of Materials Chemistry C（2023）
摘要
The phonon dispersion of mechanically exfoliated two-dimensional (2D) HfS2 is investigated through angle-resolved Raman spectroscopy and supported by first principle density functional theory (DFT) calculations. The Raman spectra show four...
