A method to restore the intrinsic dielectric functions of 2D materials in periodic calculations
Guang Yang, Shang‐Peng Gao
Abstract
from a monolayer to bulk are also calculated by solving the Bethe-Salpeter equation and they show strong anisotropy. The present method shows better agreement with the experimental results compared to previous calculations and demonstrates enormous potential to investigate the dielectric and optical properties of other 2D materials extensively and quantitatively.
