摘要：

Visible luminescence has been obtained from ensembles of defect-free, InxAl(1-x)As islands of ultrasmall dimensions embedded in AlyGa((1-y))As cladding layers, These structures were grown by molecular beam epitaxy and studied with low-temperature photoluminescence (PL) and transmission electron microscopy. Visible luminescence is produced using various compositions of InxAl((1-x))As/AlyGa((1-y))As. Quantum dot size distributions, planar densities, dot heights, and wetting layer thicknesses are presented and correlated with the PL spectra. (C) 1995 American Institute of Physics.
