Using the simple model of evenly spaced kink distribution on a single straight step in the case of an ideally stoichiometric A—B crystal, the differential equations for the stationary distributions of A and B adatoms are estabilshed and they are solved in terms of the retardation factors. For the chosen model, the potential function of the components are periodic. The total flux of A and B adatoms going to the kink are separately calculated and the rate of advance of the straight step is determined as a function of their respective supersaturations.
