Data have been taken on sound speed in GeTeAs alloys as a function of pressure and of temperature. Such data reveals the mechanical properties of the semiconducting glasses to be quite similar to those of conventional glasses. Measurement of pressure effects on dc resistivity confirm the earlier results of Fagen, et al. ac experiments are incomplete at present. Correlations between the glass transition Tg and electrical activation reported by Krebs are used to predict the trend of Tg with pressure.
