| 英文摘要 | Inas self-assembled quantum dots(qds) covered by 3-nm-thick inxga1-xas(0 less than or equal tox less than or equal to0.3) capping layer have been grown on gaas(100) substrate. transmission electron microscopy shows that ingaas layer reduces the strain in the inas islands,and atomic force microscopy evidences the deposition of ingaas on the top of inas islands when x = 0.3.the significant redshift of the photoluminescence (pl) peak energy and the reduction of pl linewidth of inas quantum dots covered by ingaas are observed. in addition,ingaas overgrowth layer suppresses the temperature sensitivity of pl peak energy. based on our analysis, the strain-reduction and the size distribution of the inas qds are the main cause of the redshift and temperature insensitivity of the pl respectively. |
