The temperature dependence of time-averaged hole drift mobility in As/sub 2/S/sub 3/ derived from PA measurements

Abstract

The time-averaged hole drift mobility in As/sub 2/S/sub 3/ glass was studied in the range 77-330 K on the basis of temperature dependence of steady-state photoinduced absorption. The hole mobility was found to be thermally activated at high temperatures, of the order of 10/sup -10/ cm/sup 2//V sec at 300 K and almost temperature independent below /spl sim/130 K.
