Abstract
We propose a model of a non‐one‐dimensional nanometer resonant tunneling device consisting of two quantum dots and three leads for which a small applied voltage can switch off the current between leads 1 and 2 and simultaneously switch on the current between leads 1 and 3. The switching device proposed is based on the effect of exponentially narrow current dip discovered in the present letter.
