Abstract:Step meandering during growth of gallium nitride (0001) surface is studied using kinetic Monte Carlo method. Simulated growth process, conducted in N-rich conditions are therefore controlled by Ga atoms surface diffusion. The model employs dominating four-body interactions of Ga atoms that cause step flow anisotropy during growth. Overall kinetics and shape selection features of step meandering are analyzed assuming their dependence on the external particle flux and on the temperature. It appears that at relat… Show more
