| Popis | The displacement field in and around periodically arranged quantum wires embedded in a crystalline matrix is calculated analytically for an arbitrary finite thickness of the cover layer. A good agreement is obtained between measured x-ray-diffraction peaks of a wire structure and kinematical calculations with the displace-ment field derived in the paper. The strain and quantum size effects on the photoluminescence line shift are found to be comparable, due to small width ~35 nm of the wires. |
