Structural and optical properties of noncentrosymmetric quaternary crystal AgCd2GaS4

Abstract Single crystals of AgCd 2 GaS 4 have been created by melting technique and single crystal growth using AgGaS 2 as a solvent. Real defect structure of stoichiometric crystals has been studied by transmission electron microscopy. Chemical composition variations and optical transparency range λ = 0.63 – 13 μ m have been measured for a AgCd 2 GaS 4 single crystal with dimensions of 40 mm in length and 9 mm in diameter.
