Abstract

Ternary Si15Ge (Ga)5Te80, Si19.7Te78.7Se1.6, Si19.2Te76.8Se4, and Ge19Te 72Se 9 telluride glasses were synthesized. Electrical, acoustic, acoustooptical properties, and the dispersion of optical transmittance of these films were studied in a wide range of temperatures and frequencies. Comparative analysis of the results obtained is performed. Possible mechanisms of the observed phenomena are discussed. It is shown that Ge19Te72Se9 aloy is quite competitive with Si20Te80 a loy for the fabrication of highly efficient acoustooptical devices with a wide range of applications in the medium IR spectral region (2–12 m)..
