Abstract

Electronic and optical properties of the infrared crystal LiGaS₂ are studied by both experimental and theoretical methods. Based on the X-ray photoelectron spectroscopy measurements, the electronic structures of Ga 3d orbitals are corrected by the GGA+U methods. Linear and nonlinear optical parameters of LiGaS₂ are determined by the first-principles theory and compared with earlier published experimental results. Good agreement is obtained between theoretical and experimental parameters.
