Ab-initio CrI3 Electronic Structure and Raman Spectra

ORAL

Abstract

First principles calculations with density functional theory are used to predict the phonon spectrum and Raman activity for chromium-triiodide (CrI3) in the high- and low-temperature crystal structures (C2/m and R-3, respectively). Comparison is made between bulk and monolayer samples. The results are used to study the effects of strain, polarization, and incident angle on Raman activity.
