Switching Nano-Device based on Rabi Oscillations

Abstract

We consider a potential landscape composed of a well region separated from a "free" region by a barrier, such that one bound state and one quasi level exist in the well. A particle initially in the ground state can be activated to the quasi level by application of a micro wave field, and subsequently tunnel in the free region. The wave function is then emitted by "bursts" after each Rabi oscillation is completed, and the leakage current can be controlled by varying the amplitude of the external field, the barrier height/width, and the frequency mismatch.
