摘要：
A self-organized InAs/GaAs quantum dot (QD) array is doped with Mn. The effect of the Mn concentration on the morphology and QD luminescence properties is investigated. It is found that Mn deltadoping of the GaAs buffer layer before QD growth with a layer concentration of 10(14) cm(-2) leads to the formation of an array of large QDs with variable composition In (x) Ga1 - x As. The effect is explained within a model of In and Ga atom interdiffusion.
