Dispersion of the linear and nonlinear optical susceptibilities of disilver germanium sulfide from DFT calculations
Original language description
The dispersion of the linear and nonlinear optical susceptibilities is calculated for disilver germanium sulfide (Ag2GeS3) using the all-electron full potential linearized augmented plane wave (FP-LAPW) method. Calculations are performed with four exchange correlations namely local density approximation (LDA), general gradient approximation (GGA), Engel-Vosko generalized gradient approximation (EVGGA), and modified Becke-Johnson potential (mBJ). Our calculations give a band gap of 0.40 eV (LDA), 0.42 eV(GGA), 1.03 eV (EVGGA), and 1.30 eV (mBJ) in comparison with our measured gap (1.98 eV). The mBJ exchange correlation gives the best agreement with experiment. We find that the calculated linear optical susceptibilities of Ag2GeS3 show considerable anisotropy which is useful for second harmonic generation and optical parametric oscillation. To analyze the spectra of the calculated chi (113) ((2)) (omega), chi (232) ((2)) (omega), chi (311) ((2)) (omega), chi (322) ((2)) (omega), and chi
