We analyze the development of compositional and surface non uniformities during the growth of strained alloy films, for the case of different surface mobilities of the alloy components. We find that a difference in surface mobilities can completely suppress the stress-driven morphological instability. The stabilization occurs under compressive misfit when one atomic species is both large and fast relative to the other, and similarly under tensile misfit when one species is small and fast.
