An influence is studied of electromagnetic radiation on epitaxial stru
cture growing processes. Highpower xenon lamp, pulse and continuouse U
V laser were used in experiments on A B-4(6) films growing. The condit
ions of obtainind of nonplanar film structures are detemined. Properti
es of filmes doped with indium, including transient layer between the
film and the substrate are studied, as well as film peeling processes.
The model of processes going on the crystallization surface is consid
ered and the necessity to take defects kinetics into account when anal
izing photostymulated epitaxy is shown.
