KINETICS OF CW LASER-INDUCED CRYSTALLIZATION AND OXIDATION OF THIN, SB, SE, AND SB2SE3 FILMS IN AIR

Thin films of Sb, Se and Sb2Se3 are deposited onto glass and irradiated by a cw-Ar+ laser beam. The kinetics of crystallization and oxidation are traced via the time dependence of optical reflectivity and temperature, T, of the irradiated zone. For Sb2Se3, transformations start abruptly when T attains a critical value, T(c), independently of the laser beam power. These T(c) values are comparable to the ones observed under furnace annealing conditions.
