Photon-assisted electron transport for resonant tunneling has been investigated by using a current formula developed based on the nonequilibrium Green's function technique. We have studied the external frequency dependence as well as the energy level position dependence for the resonant ac tunneling

## Abstract In the present paper a new model for the transport through membranes, introduced previously by Hosur, is considered. In this model, the membrane is assimilated to a potential barrier, and the material flow through the membrane is determined from the transmission coefficient of the barri
Making use of the equation of motion method and Keldysh Green function technique, we obtain a general current formula for a quantum-dot-ring with one of the dots connected to two electron reservoirs under a DC bias voltage. The transmission probability TðoÞ as a function of electron o curve is prese
We apply the theory for the transmission probability T( ) through small interacting systems, which was formulated based on the Kubo formalism in the previous study, to a series of quantum dots described by the N -impurity Anderson model. Speciÿcally, we calculate T( ) for N = 2 with the order U 2 se
## Abstract Electron tunneling through a spin‐split discrete level of an interacting quantum dot coupled to two ferromagnetic electrodes with non‐collinear magnetizations is investigated theoretically by means of the nonequilibrium Green function approach. It is shown that the spin splitting of the
