We investigate the photoconductance through a double quantum dot or 'artificial molecule' induced by a broadband millimeter wave source. This source functions as a heterodyne interferometer, consisting of two nonlinear transmission lines generating harmonic output in the range of 2-400 GHz, and, bei

In this paper we review our recent study of coherent electronic properties of coupled twodimensional quantum dot arrays using numerical exact-diagonalization methods on a Mott-Hubbard type correlated tight-binding model. We predict the existence of a novel kind of persistent current in a two-dimensi
Results of transport measurements on double quantum dots in series with a weak mutual coupling are presented. Samples have been obtained by delineating two-dimensional electron gas in modulation-doped AlGaAs=GaAs with independently bias-tunable, 100 nm wide, Schottky-gates formed by an electron beam
