Optical absorption and disorder in the As40S60 − x Se x vitreous alloys

Optical absorption and disorder in the As40S60 − x Se x vitreous alloys

The absorption edge spectra of vitreous alloys in the As-S-Se system are measured in the temperature range 77-300 K. The parameters of the fundamental absorption edge and the electron-phonon interaction in As^sub 40^S^sub 60 - x^Se^sub x^ (x = 0-40) glasses are determined, and the influence of the c...

Description
Summary:The absorption edge spectra of vitreous alloys in the As-S-Se system are measured in the temperature range 77-300 K. The parameters of the fundamental absorption edge and the electron-phonon interaction in As^sub 40^S^sub 60 - x^Se^sub x^ (x = 0-40) glasses are determined, and the influence of the compositional disorder on these parameters is investigated. The contributions of the static structural and temperature disorders to the smearing of the fundamental absorption edge of the alloys under study are evaluated.[PUBLICATION ABSTRACT]
