介观物理学

依据介观物理学的基本概念、半经典电子输运理论和碳纳米管的电子结构，对非掺杂直状金属型单层碳纳米管（SWNTs）的电导特性进行理论研究，计算表明；

According to the fundamental concept of mesoscopic physics , semi-classical electronic transport theory and the electronic structure of carbon nanotube , the conductance property of undoping metallic single-wall carbon nanotubes ( SWNTs ) was studied theoretically .

介观物理学是从20世纪80年代发展起来的物理学的一个分支学科。

Mesoscopic physics has been developed a branch of physics from the eighties in the twentieth century .

论文首先介绍了介观物理学和量子输运理论的发展；随后综述了分子电子学的一些进展，包括近年来的部分研究热点以及未来的发展的可能方向。

At first , the development of the mesoscopic physics and the quantum transport theory is outlined . Then we review some recent advances in molecular electronics , including some interesting topics and possible development directions .
