Equilibrium Composition-Modulated Structures in Epitaxial Films of Semiconductor Alloys

Abstract

Here we study the thermodynamic stabllity of an alloy A(1-cB(c)C in the epitaxial film against fluctuations of alloy composition. We consider a film on the (001)-substrate of a cubic crystal and we focus on the situation where the homogeneous alloy with the compostion c=c-bar is lattice matched to the substrate. Both the substrate and the epitaxial film are elastically anisotropic cubic crystals having equal elastic modulus tensors.
