介绍了单电子泵的工作原理 ,讨论了如何利用库仑阻塞和单电子隧穿实现对单电子泵中单个电子运动的控制 ,从而给出它的相图 ,并由此得到了单电子泵的一个重要用途 ,即控制微小电流 .指出栅极可能引入的随机电荷对单电子泵的应用并无影响 .
The working principle of the single electron pump is introduced. How to control the single electron movement in the single electron pump by Coulomb blocking and single electron tunneling is discussed. The phase diagram of the single electron pump is given, and a single electron pump It is important to control the tiny currents, pointing out that the possible random charge introduced at the gate has no effect on the application of the single electron pump.
