| 英文摘要 | In this work, inas quantum dots (qds) grown on a linear graded ingaas metamorphic buffer layer by molecular beam epitaxy have been investigated. the growth of the metamorphic buffer layers was carefully optimized, yielding a smooth surface with a minimum root mean square of roughness of less than 0.98 nm as measured by atomic force microscopy (afm). inas qds were then grown on the buffer layers, and their emission wavelength at room-temperature is 1.49 mu m as measured by photoluminescence (pl). the effects of post-growth rapid thermal annealing (rta) on the optical properties of the inas qds were investigated. after the rta, the pl peak of the qds was blue-shifted and the full width at half maximum decreased. |
