| 英文摘要 | We report a quantum dot (qd) ensemble structure in which the in-plane arrangements of the dots are in a hexagonal way while the dots are also vertically aligned. such a distinct lateral ordering of qds is achieved on a planar gaas(l 0 0) rather than on a prepatterned substrate by strain-mediated multilayer vertical stacking of the qds. the analysis indicates that the strain energy of the lateral island-island interaction is minimum for arrangement of the hexagonal ordering. the ordered dots demonstrate strong photoluminescence (pl) emission at room temperature (rt) and the full width at half maximum of pl peak at rt is only 50 mev.
