Relaxation and thermoinduced processes in glassy HgSe(x)-GeSe₂(₁-x) alloys

Abstract

Spectra of absorption in glassy HgSe(x)-GeSe₂(₁-x) (x = 42, 46, 54) alloys were studied. Sustained relaxation processes - a shift of the optical absorption edge to longer wavelength - were detected. Also observed was a thermoinduced reversible process when the absorption edge is shifted in the same direction after the samples have been annealed at 100 °С.
