| 英文摘要 | Inas quantum dots have been grown by solid source molecular beam epitaxy on different matrix to investigate the effect on the structure and optical properties. high density of 1.02 x 10(11) cm(-2) of inas islands on in0.15ga0.85as and in0.15al0.85as underlying layer has been achieved. atomic force microscopy and photoluminescence spectra show the size evolution of inas islands on in0.15ga0.85as underlying layer. a strong 1.3 mum photoluminescence from inas islands on in0.15ga0.85as underlying layer and with ingaas strain-reduced layer has been obtained. single-mirror light emitting diode structures with inas quantum dots capped by ingaas grown on ingaas layer as active layer were fabricated and the corresponding radiative efficiency was deduced to be as high as 20.5%. our results provide important information for optimizing the epitaxial structures of 1.3 mum wavelength quantum dots devices.
