Fano effect of a laterally coupled vertical triple quantum dot system

doi:10.1088/1674-1056/22/2/027306

Abstract Using the nonequilibrium Green's function technique, electron transport through a laterally coupled vertical triple quantum dot is investigated. The conductance as a function of electron energy is numerically calculated. The evolution of the conductance strongly depends on the configuration of dot levels and interdot coupling strengths.

Keywords: nonequilibrium Green's function Fano effect quantum dot electron transport
