Optical properties of SiC nanosheet

Electronic and optical properties of silicon carbide nanosheet (2D monolayer) have been studied using full potential linearized augmented plane wave (FP-LAPW) method with the generalized gradient approximation (GGA) within WIEN2k package. The dielectric tensor is derived within the random phase approximation (RPA). The electronic structure and the optical properties of SiC nanosheet such as the dielectric function, reflectivity, absorption coefficient and optical conductivity are calculated for both perpendicular and parallel electric field polarizations.
