摘要
所谓半导体量子点的自组织生长,是指具有较大晶格失配度的两种材料,依靠自身的应变能量,并以 Stranki Krastanov( S K) 生长模式,在衬底表面上形成的具有一定形状、尺寸和密度分布的自然量子点结构。本文主要介绍了纳米量子点的自组织生长,自组织生长量子点的发光特性及其在光电器件中的应用。
The self organized growth of semiconductor quantum dots are spontaneous quantum dot structures formed by Stranki Krastanov growth mode. In general, the formed semiconductor quantum dots are lattice mismatched systems with substrate materials, and they have certan size, shape and density. This paper introduces ultimate principles of self organized growth on semiconductor quantum dots, self organized growth machnism on various quantum dots, optical properties and its applications in photoelectronic devices.
