Abstract
We develop a theoretical model for step flow growth of multilayer films, taking into account the interlayer step-step interaction induced by misfit strain. We apply the model to simulate the growth of strain-compensated short-period superlattices. Step-bunch ordering improves in successive layers, leading to self-organized growth of a lattice of quantum wires. This quantum-wire array has some similarities to the “lateral composition modulation” observed experimentally in short-period superlattices.Keywords
