Abstract
The electrical and optical properties of amorphous GeSe2 and Ge(0.9)7Se(2)C d(0.03) films have been investigated. Cd incorporation affects greatly the thermal activation energy and the pre-exponential factor but has little eff ect on the optical gap. The results are discussed in terms of the effect of Cd atoms oil the anion homopolar bond states at raft edges.
