Electronic Transport Phenomena in Novel Quantum Dot Structures

由于微制造技术的进步，最近凝聚态物质实验者已经可以将载流子限制到降维。创造三维受限结构的能力，被称为“量子点”，引起了人们对人工构建的低维系统的浓厚兴趣。这些结构类似于半导体原子，能级可以通过限制势来调节。这一提议旨在更好地理解这些系统中的电子输运，并提出了各种新的结构来阐明低维量子输运的相关物理。

Carrier confinement to reduced dimensions has recently become accessible to condensed matter experimentalists due to advances in microfabrication technology. The ability to create three- dimensionally confined structures, termed "quantum dots", has generated intensed interest in the investigation of artificially structured low dimensional systems. These structures are analogous to semiconductor atoms, with energy level tunable by the confining potentials. This proposal is aimed at a better understanding of the electronic transport in these systems and proposes a variety of novel structures to elucidate the relevant physics of low dimensional quantum transport.
