Paper Abstract

Thin layers of polycrystalline antimony and amorphous selenium are successively deposited onto a glass substrate. Under specific CW Ar+ laser irradiation conditions in these Sb/Se bilayered films, optical microscopy evidence for a spherulytic crystal growth is obtained. Phase forming is characterized by low angle X-ray diffraction, reflection high energy electron diffraction, energy dispersive X-ray analyses, and Auger spectroscopy. It is shown that, though depending on the laser irradiation conditions, the final spherulytic growth in the irradiated Sb-Se films stems from the Sb-innermost layer crystallization process. Spectacular trans-crystallization takes place through the film during laser treatment of the bilayer. An attempts at modeling this CW-laser induced recrystallization is proposed.
