Photoinduced phenomena in nano-dimensional glassy As 2 S 3 films

Photoinduced anisotropy in nano-dimensional (ND) thin films ( 1µm). ND As2S3 films are shown to function also as efficient photoresists. Preliminary model based on two exponential rate processes involving defects generation and stabilization is proposed explaining the main features of the photoinduced phenomena. These observations widen the range of applications of chalcogenide glassy films such as for higher capacity of optical data storage and for the photoalignment of liquid crystals.
