Abstract
Complex photoconductive measurements of the current through a double quantum dot enable us to monitor effects of coherent electron transport in the suppression of the rabi oscillations of this “artificial molecule.” The current is induced by a new broadband millimeter wave source functioning as a heterodyne interferometer, which consists of two nonlinear transmission lines generating harmonic outputs in the range 2–400 GHz, and, being coherent, allows tracking the induced current through the sample in both magnitude and phase.Keywords
