| 1. | As an example , we numerically investigated the transport properties of a four - quantum - dot ring . we found that the resonant tunneling spectrum depends on the arrangement of the single - dot energy level , the interdot tunnel coupling amplitude between neighbouring dots , and the tunnel coupling between dots and leads
在数值计算部分,作为体系的一个特例,我们首先详细的研究了由四个量子点耦合成的量子点环中的电子输运,确定了三种结构的共振隧穿谱线对单量子点能级的不同组合情况以及相邻量子点之间的耦合强度的依赖关系。 |
