中文摘要 | a novel line-order of inas quantum dots (qds) along the [1, 1, 0] direction on gaas substrate has been prepared by self-organized growth. after 2.5 monolayer inas deposition, qds in the first layer of multi-layer samples started to gather in a line. owing to the action of strong stress between layers, almost all the dots of the fourth layer gathered in lines. the dots lining up tightly are actually one-dimensional superlattice of qds, of which the density of electronic states is different from that of isolated qds or quantum wires. the photoluminescence spectra of our multi-layer qd sample exhibited a feature of very broad band so that it is suitable for the active medium of super luminescent diode. the reason of dots lining up is attributed to the hill-and-valley structure of the buffer, anisotropy and different diffusion rates in the different directions on the buffer and strong stress between qd layers.
