Original Abstract

The paper analyzes the depth and spacing of cracks in a tensile strained In0.25Ga0.75As epitaxial layer on a InP substrate using the minimum energy theorem. The elastic anisotropy of both the layer and the substrate is considered. The concept of weight function obtained numerically by means of detailed FEM is employed.
