Sy. Karpov et Ma. Maiorov, MODEL OF THE ADSORPTION DESORPTION KINETICS ON A GROWING III-V COMPOUND SURFACE/, Surface science, 393(1-3), 1997, pp. 108-125
A kinetic approach for surface processes occurring on growing III-V co
mpound (001)-oriented surfaces is proposed. The model assumes the proc
esses proceeding in a single adsorption layer. Four kinetic constants
are introduced to describe species desorption, incorporation of atoms
from adsorption layer to crystal and decomposition of the crystal. The
approach allows one to determine growth rate of the crystal, conditio
ns of extra phase appearance on the surface, minimum temperature of ep
itaxy and temperature of congruent evaporation, sticking coefficients
of Group V species on the growing surface, etc. The proposed model is
verified by comparing the theoretical predictions with available exper
imental data obtained for the GaAs(001) surface. (C) 1997 Elsevier Sci
