中文摘要：
半导体量子结构中量子过程与调控的实验与理论研究是当代凝聚态物理学科前沿。本重点项目围绕以新型半导体纳米线、量子点、纳米环和纳米螺旋状超结构为代表的半导体纳米结构，以结构设计和系统可控生长、电子能带及结构操纵、磁场和电场等对量子输运过程的调控为研究主线，实验与理论密切结合，深入研究新型一维半导体受限系统中的电子结构、量子干涉效应、量子耗散、量子退相干特性和外场对量子共隧穿和自旋输运等过程的调控及机理；构建多种基于半导体纳米线、量子点、纳米环和纳米螺旋的量子介观系统原型器件，探索研究其潜在的纳电子器件应用；探寻体系中新奇输运现象及规律，期望形成若干量子调控新概念、新观点和新途径。积极参与学科前沿的国际学术竞争，创立有自己特色的实验和理论体系，形成有一定国际影响力的研究小组。
