Article Description

Photoluminescence in strained InGaAs-GaAs single heterostructures, grown by molecular-beam epitaxy, is studied, and the critical layer thickness is determined for a range of In mole fractions. The critical thicknesses are compared with similar values measured on the same layers by double-crystal x-ray diffraction. Both techniques give essentially the same results. The photoluminescence line shapes are discussed for layer thicknesses below and above the critical thickness.
