Chalcopyrite semiconductor compounds, MIMII’E2 (MI = Cu, Ag; M’II = Al, Ga, In; E = S, Se, Te), have been prepared by microwave irradiation of appropriate mixtures of the pure elements in a domestic microwave oven and characterized by X-ray diffraction (XRD) and energy-dispersive X-ray (EDX) analysis. Alloys of the type CuInSxSe2, and CuInSexTe2, (0 < x < 2 ) analyzed by XRD show that solid sol...

The electronic structure, linear and nonlinear optical properties have been calculated for CuInX2 (X = S, Se, Te) chalcopyrite-structure single crystals using the state-of-the-art full potential linear augmented plane wave (FP-LAPW) method. We present results for band structure, density of states, and imaginary part of the frequency-dependent linear and nonlinear optical susceptibilities. We fi...
