Abstract

Contactless transient photoconductivity measurements in intrinsic and n-type a-Si:H were performed at 220 °C and at room temperature where also rapidly quenched films were investigated. In undoped samples the measurements suggest thermally induced structure changes which lead to an increase of the effective electron lifetime. In n-type samples the effective electron lifetime decreases with temperature, what may be explained by an increase of the hole emission rate with temperature.
