Quantum Transport in Graphene Quantum Dots

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.

Conductance in quantum wires by three quantum dots arrays

A noninteracting quantum-dot arrays side coupled to a quantum wire is studied. Transport through the quantum wire is investigated by using a noninteracting Anderson tunneling Hamiltonian. The conductance at zero temperature develops an oscillating band with resonances and antiresonances due to constructive and destructive interference in the ballistic channel, respectively. Moreover, we have fo...
