摘要
We have systematically studied the growth modes of InxGa1-xAs on GaAs(001) (0less than or equal toxless than or equal to0.5) under As-deficient conditions. The InxGa1-xAs film coherently grows in a layer-by-layer mode, with a significant amount of In atoms being segregated to the growing surface. The In segregation results in the depletion of In in the InxGa1-xAs film, so that the strain at the coherent interface is reduced. The growth under higher As fluxes suppresses the In segregation and induces the formation of the relaxed InxGa1-xAs islands.
