摘要

We discuss the growth of In_xGa_1-xP quantum dots on nominally (100)-oriented GaP substrates by low-pressure metal organic vapor phase epitaxy. Parameters like the growth temperature, thickness of the InGaP layer, strain, via the indium composition of In_xGa_1-xP, and the post-growth ripening time have been varied to study their effect on the growth of self-assembled InGaP quantum dots in Stranski-Krastanow mode. Under optimized conditions quantum dots with lateral dimension ~5 nm and a density >5 nm and a density > 10~10 cm~2 have been achieved. Surface photovoltage spectroscopy is shown to be a convenient and sensitive technique to monitor the various stages in the growth of quantum dot structures.
