摘要

The kinetic model, describing homoepitaxial growth on a (001)GaAs surface within the framework of the kinetic mean field equations, is offered. The following elementary surface processes are included in consideration; As_4 adsorption-desorption, As_4~* bimolecular reaction, incorporation of As_2~(chem) into lattice sites. The model gives the adequate description of the experimental results on growth rate for low and high pressures. Numerical values of elementary constants are obtained.
