Strain Distributions of Self-Assembled CdxZn1-xTe Quantum Wires Grown on ZnTe Buffer Layers

The shape of CdxZn1-xTe/ZnTe quantum wires (QWRs) was approximately modeled to be a half-ellipsoidal cylinder on the basis of an atomic force microscopy image. The normal strain components of the CdxZn1-xTe/ZnTe QWRs were numerically calculated by using a finite-difference method (FDM) taking into account shape-based strain effects. The strain potential energies of the conduction band and the heavy-hole band for the CdxZn1-xTe/ZnTeQWRs were calculated by using a FDM taking into account the three kinds of normal strain components.
