Nonlinear Conductance in Resonant Tunneling.
نویسنده
چکیده
A multiterminal conductance formula describing resonant tunneling through an interacting mesoscopic system is derived and used to investigate the nonlinear conductance of a quantum dot. An explicit gauge-invariant expression for the I-V characteristic which depends sensitively on the full capacitance matrix is obtained. A voltage probe is found to have a dramatic effect on the nonlinear conductance. [S0031-9007(96)01247-1]

Nonlinear resonant tunneling through an Anderson impurity at low temperature.
The problem of nonlinear resonant tunneling through an Anderson impurity is investigated in this Letter using a combined approach of Keldysh f'ormalism and 1/iV expansion at zero temperature. We find that to order l/iV, the Kondo resonance is not destroyed by any finite potential difference between external probes. The resulting one-electron Green's functions and differential conductance are pr...
متن کاملEffect of asymmetric quantum dot rings in electron transport through a quantum wire
The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...

متن کاملObservation of Unitary Conductance for Resonant Tunneling with Dissipation
We investigate tunneling through a resonant level formed in a carbon nanotube quantum dot contacted by resistive metal wires. These contacts create a dissipative environment for the electrons tunneling across the nanotube, thus suppressing the tunneling rate. We study the shape of the resonant peak in the nanotube conductance, with the expectation that the peak width and height, both dependent ...

It is shown that the low energy spectrum of mesoscopic superconductors coupled by Josephson interaction can be probed by two-electron tunneling from a normal electrode. The Andreev reflection in the NS junction of a normal-superconductor-superconductor double junction (NSS transistor) provides a unique spectroscopic tool to probe the coherent Cooper pair tunneling and the energy spectrum of the...
