The effect of temperature and light polarization on the photoinduced mass transport in films of arsenic-selenium and antimony-selenium systems was investigated. It was shown that the rate of mass-transport of film material induced by laser radiation increases significantly with increasing temperature. A model of alternating photoinduced mass transport of ChVS films material based on Dember's lateral photoeffect is proposed. The method of atomic force microscopy revealed that the interaction between photosensitive amorphous chalcogenide films deposited on arrays of gold nanoparticles with varying degrees of ordering or on nanosized gold films and localized near-field radiation arising from the irradiation, mass-transport and leads to nanostructuring of the film surface. It was established that the rate of formation of nanoreliefs and their morphology depend on the recording temperature and the polarization of the laser beams.
