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

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
Photon-assisted electron transport for resonant tunneling has been investigated by using a current formula developed based on the nonequilibrium Green's function technique. We have studied the external frequency dependence as well as the energy level position dependence for the resonant ac tunneling
Using a six-band k Γ p formalism we investigated the single-particle hole states in the double quantum dots made of two identical, vertically stacked, Ge/Si nanoclusters. The elastic strain due to the lattice mismatch between Ge and Si was included into the problem via Bir-Pikus Hamiltonian. As cons
