摘要：

Illumination of amorphous arsenic chalcogenides with band-gap light induces photodarkening and volume expansion, In addition to metastable changes, which persist after the light is switched off, transient effects occur during and after illumination, We present measurements of these metastable and transient effects in evaporated films of a-As2S3, a-As2Se3 and a-Se. The results are discussed in terms of a model in which, on photoexcitation. layer- or chain-like clusters of atoms expand and slip relative to each other. (C) 2002 Elsevier Science B.V.
