Synthesis, structural, electronic and linear electro-optical features of new quaternary Ag2Ga2SiS6 compound

Manuscript present the technology of growth and investigation of properties a new quaternary compound Ag2Ga2SiS6 including the detailed study of the phase equilibria in the AgGaS2-SiS2 system to determine the physico-chemical conditions of its formation. We examined crystal structure of the compound by X-ray powder method, its electronic structure by XPS method. Finally we have found these crystals like promising material for nonlinear optical, electrooptical and piezoelectric applications.292
