Abstract

Abstract Results of theoretical and experimental study of ArF-excimer-laser-induced recrystallization of monocrystalline Si(100) surface are presented. The theoretical model of laser-induced thermal processes including the density changes due to thermal expansion and phase-changing is introduced. Comparison of calculated data with in situ LEED analysis indicate a significant correlation between laser-induced high solidification velocity and/or undercooling and crystalline structure of the irradiated surfaces.
