Raman Scattering Modification in Monolayer Arsenene Controlled byStrain Engineering

doi:10.19596/j.cnki.1001-246x.8057

Abstract

Abstract: Raman spectra of monolayer arsenene with external strain are determined with density functional theory. Due to lower structural symmetry, deformation induced by external strain regulates Raman mode splitting and leads to Raman mode shifts as well. Our calculations suggest that the structural deformation induced by external strain can be clearly identified by Raman scattering.

Key words: Raman spectra, first-principle calculation, strain, arsenene, two-dimensional layered material
