Abstract

Optical Modulation Spectroscopy was studied at room temperature in three a-Si:H films with different deposition temperatures. The gap density of states is largely influenced by this parameter. The results may be explained with a sharp distribution of D° (neutral dangling bond) states and a broad distribution of D- (negatively charged dangling bond) states.
