摘要： 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.
