Current Switch by Coherent Trapping of Electrons in Quantum Dots
arXiv:cond-mat/0009229 · doi:10.1103/PhysRevLett.85.4148
Abstract
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.
