Analytic expressions are derived for the strain field due to a lattice-mismatched quantum wire buried in an infinite medium whose cross-section is composed of any combination of line elements and circular arcs. Expressions for the strain field for rectangular, triangular and circular quantum wires are found confirming published results. For the rectangular(More)
Strained layers are incorporated into many electronic devices and particularly into semiconductor lasers. These strained layers can relax, both elastically and plastically, which often impairs the performance of the device. This thesis presents several methods for calculating elastic strain relaxation: a Fourierseries method for stresses imposed on the(More)
