摘要：

Photo-induced thickness changes in obliquely deposited amorphous As2S3 and GeSe2 films have been measured to determine the mechanisms of changes during illumination. For As2S3, the thickness increases and then decreases and saturates after some time. There is a decrease followed by saturated change even after the illumination is switched off. On the other hand, GeSe2 has a continuous decrease of thickness with time, which remains constant after the illumination is turned off. The difference in these properties between As2S3 and GeSe2 films is discussed in terms of different structural units for these films (layered for a-As2S3 and three-dimensional for a-GeSe2).
