摘要：

Long-wavelength photoluminescence at 1.35 mu m has been measured from an InGaAs quantum-well heterostructure deposited on disk-shaped InGaAs (x(In) = 0.05) compliant-film membranes. Strain-induced warping is avoided by utilizing a single pedestal to suspend each compliant-film disk over a GaAs substrate. Cathodoluminescence (CL) spectra verify the long-wavelength emission, and panchromatic CL images reveal that strong emission occurs only on compliant film structures supported by 1-mu m-diam pedestals.
