Optical properties of a wrinkled nanomembrane with embedded quantum well

Nano Lett. 2007 Jun;7(6):1676-9. doi: 10.1021/nl070653e. Epub 2007 Apr 27.

Abstract

A wrinkled nanomembrane with embedded quantum well (QW), fabricated by the partial release and bond back of epitaxial layers upon underetching, is investigated by spatially resolved micro-photoluminescence spectroscopy. From the observed QW transition energies and calculations based on the linear deformation potential theory, we find that the bonded back regions are fully relaxed and act on the strain state of the wrinkled QW. Light emission enhancement observed in the wrinkled QW is explained by interference contrast theory.
