Abstract :
We study the mechanism of ordered growth of InAs quantum dots (islands) on a GaAs/InP substrate in theory and point out that the tensile strain can be used to control InAs/InP selfassembled quantum dots arrangement. Photoluminescence spectrum, and atomic force microscopy images have been investigated. In the experiment, ordered InAs islands have been obtained and the maximum density of quantum dots is 1.6×1010 cm-2 at 4 monolayers InAs layer.
