Abstract
In order to see the medium range order in Ge 1-x(Se, or S) x glass, pressure as well as composition dependence of vibrational spectra is investigated. It is shown that Raman spectrum with perpendicular polarization in Ge(Se, or S) 2 is well reproduced by the density of states calculation for a relaxed large molecular fragment assuming “outrigger raft”. The A 1 band shifts to the high energy side with increasing pressure. The pressure coefficient is very small at x= 2 3 . The Raman spectra due to Se chains show appreciable softening at high pressures. The characteristic spectra due to S 8 rings disappear at not more than 20 kbar. The glass containing tin atoms is found to be of great use to understand the structure of the chalcogenide glasses.
