This article reviews the application of the non-equilibrium Green's function formalism to the
simulation of novel photovoltaic devices utilizing quantum confinement effects in low …

Correlation effects in the transport properties of a single quantum level coupled to electron
reservoirs are discussed theoretically using nonequilibrium Green functions approach. Our …

We report a systematic experimental study of charge transport in nanometer-scale double-
barrier resonant-tunneling devices. Asymmetric heterostructure material was used so that …

We investigate low-temperature transport through two identical vertically coupled quantum
dots in a triple-barrier heterostructure. The current-voltage curve exhibits two series of …

Transport through two quantum dots in parallel is studied theoretically in the presence of a
magnetic flux between dots and in the limit of large one-electron level separations in each …

The equation of motion for nonequilibrium Green functions is derived within the framework of
the Schwinger and Keldysh formalism of perturbation expansion. For nonequilibrium …

We present a general theoretical formulation, based on nonequilibrium Green's functions, for
nonlinear dc transport in multiprobe mesoscopic conductors. The theory is gauge invariant …

The coherent transport through a coupled-quantum-dot system with strong intradot
interaction is investigated by the nonequilibrium Green's-functions method. The …

We investigated Coulomb repulsion effects in nonadiabatic (diabatic) two-electron tunneling
through a redox molecule with a single electronic level in a symmetric electrochemical …
