Abstract
The mechanism and the main features of the effect of anisotropic local melting of semiconductor surfaces which can be observed at definite regimes of homogeneous irradiation by powerful pulses of coherent and incoherent light are investigated. The dynamics of this effect was studied for the first time. Using rapid filming microphotos of the silicon surface were taken. On implanted silicon, the dynamics of reflection of the probing He-Ne laser radiation under heating with powerful optical irradiation is measured. The results can be explained by the different degree of semiconductor superheating with respect to the equilibrium temperature of melting. It is demonstrated that under certain conditions light pulse itself generates centers for the formation of liquid nuclei.
