Abstract
We discuss the relation between microscopic mechanism and macroscopic growth behavior. First, we introduce a macroscopic theory of growth behavior in semiconductor heteroepitaxy that includes the effects of the formation of Stranski-Krastanov islands and the misfit dislocations. This theory can reproduce the various types of growth behavior observed in heteroepitaxial growth. Next, we have formulated a procedure for determining the phenomenological parameters that includes atomistic informations. The critical thickness of InAs/GaAs(1 1 0) heteroepitaxy obtained by this procedure is in good agreement with the scanning tunneling microscopy (STM) observations.
