Metallorganic vapor phase epitaxially-grown AlxGa1-xAs/GaAs structures were passivated by in situ deposition of a monolayer of InP on the surface. The surface recombination was studied by photoluminescence measurements of near-surface Al0.22Ga0.78As/GaAs quantum wells. The luminescence intensity of the passivated samples increased by about five orders of magnitude for quantum wells located at less than 5 nm from the surface as compared to unpassivated samples.
