Simulation of non-equilibrium electron transport in silicon quantum wires

Non-equilibrium quantum dots: transport

The electronic transport through three-dimensionally confined semiconductor ’quantum dots’ is investigated and analyzed. The spectrum corresponds to resonant tunneling from laterally confined emitter contact subbands through the discrete three-dimensionally confined quan tum dot states. Momentum non-conservation is observed in these structures.

Effect of asymmetric quantum dot rings in electron transport through a quantum wire

The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...
