Abstract

The defects that result from light soaking a-Si Ge :H are studied over the alloy range 0<X<0.4. These defects act as recomdinltion centers with a large hole capture cross section. The creation rate for light-induced defects is independent of the Ge content for compositions investigated (x = 0 to 0.4). The transport changes that result from Ge incorporation do not result in the creation of a larger density of these centers; however, the electronic transport properties decrease with increasing Ge content. The possibility that this decrease is due to germanium clusters is explored.
