We propose a new transport mechanism through tunnel-coupled quantum dots based on the coherent population trapping effect. Coupling to an excited level by the coherent radiation of two microwaves can lead to an extremely narrow current antiresonance. The effect can be used to determine interdot dephasing rates and is a mechanism for a very sensitive, optically controlled current switch.
我们提出了一种基于相干布居囚禁效应、通过隧道耦合量子点的新型输运机制。通过两个微波的相干辐射耦合到一个激发能级会导致极窄的电流反共振。该效应可用于确定量子点间的退相速率,并且是一种实现非常灵敏的光控电流开关的机制。
