利用非平衡格林函数方法,对五个量子点连结而成的有四个终端的耦合量子点分子桥进行了理论研究和数值模拟,得出了入射电子通过耦合量子点分子桥传输到各个终端的电子隧穿概率的规律.
By using the non-equilibrium Green’s function method, the quantum dot with four terminals connected by five quantum dots is theoretically studied and numerically simulated. It is found that the incident electrons are transmitted to each terminal through the coupled quantum dot molecular bridge The law of electron tunneling probability.
