Abstract
A reduction in the mobility due to additional localization at the conduction band edge in a-SiGe:H alloys has been measured in transient photoconductivity experiments. The slope of the conduction band tail flattens as the concentration is increased, reflecting the additional chemical disorder introduced by the Ge. The neutral dangling bond density remains nearly unchanged for CGe\n\n\t\t
