摘要
自组装半导体量子点是人工设计、生长的一种具有量子尺寸效应、量子干涉效应、表面效应、量子隧穿和Coulumb阻塞效应以及非线性光学效应的新型功能材料.由于其具有晶体缺陷少、材料制备工艺相对简单等优点而在未来纳米电子器件的研制中有重要的应用价值.本文按照纵向输运、横向输运、电荷存储的顺序,扼要评述了自组装半导体量子点电子学性质的最新研究进展,并对目前存在的问题和发展前景作了分析.
Self-assembled semiconductor quantum dot is a new type of artificially designed and grown function material which exhibits quantum size effect, quantum interference effect, surface effect, quantum tunneling-Coulumb-blockade effect and nonlinear optical effect. Due to its advantages of less crystal defects and relatively simpler fabrication technology, this material may be of important value in the research of future nanoelectronic device. In the order of vertical transport, lateral transport and charge storage, recent advances in the electronic properties of this material are brefly introduced, and the problems and perspectives are analyzed.
