摘要：

InAs/GaP semiconductor quantum dots (QDs) were spontaneously formed using direct island growth (Volmer-Weber) rather than Stranski-Krastanow (S-K) growth. Structural investigations of InAs/GaP QDs suggest kinetically limited growth and show a broad size distribution Photoluminescence and cathodoluminescence spectroscopy reveal large inhomogeneous broadening with the emission peak centering at 1.7 eV, Device applications exploiting broad optical emission in QDs are discussed.
