A SIMPLE METHOD FOR CALCULATING STRAIN DISTRIBUTIONS IN QUANTUM-WIRE STRUCTURES

We present a simple method for calculating the stress and strain distr ibutions due to an initially uniformly strained quantum wire with a cr oss section of arbitrary shape buried in an infinite medium. The metho d involves the evaluation of a path integral around the boundary of th e quantum wire and is therefore considerably more straightforward to i mplement than alternative stress evaluation techniques. Published resu lts for the strain distribution due to a rectangular quantum wire are confirmed and results for a quantum wire of triangular cross section a re presented.
