中文摘要	the effects of annealing on the optical properties of inas/gaas quantum dots (qds) grown under different conditions by metalorganic chemical vapor deposition (mocvd) are studied. a lower qd growth rate leads to an earlier and faster decrease of qd photoluminescence (pl) intensity with increasing annealing temperature. which is proposed to be related to the increased qd two-dimensional (2d)-three-dimensional (3d) transition critical layer thickness at low qd growth rate. high-quality gaas cap layers grown at high temperature and a low deposition rate are shown to decrease the blueshift of the qds' emission wavelength significantly during in-situ i h annealing experiments, which is important for the fabrication of long-wavelength inas/gaas qd lasers by mocvd technique.
