Resonance tunneling of a classical particle
Physical Review E, 1996Exact solutions are obtained for the diffusion in single- and square-well potentials, by using the Laplace transform method. We compare transmission of a classical particle through one barrier of given length and through two barriers with a well between them of the same overall length.

Abstract Localized electron states in oxides adjacent to metals hybridize with conduction electron states forming interface states, which at the localized site have an amplitude resonantly enhanced over the amplitude of the conduction electron states.

Resonant tunneling in a Luttinger liquid
Physical Review B, 1993The resonant tunneling through a double-barrier structure in a one-dimensional system of interacting spinless fermions is studied. The conductance is calculated as a function of gate voltage and temperature. It is shown that even in Luttinger liquids the line shape of resonances is almost the same as that of the noninteracting Fermi liquid provided ...

Stochastic resonance in a tunnel diode
Physical Review E, 1994We study stochastic resonance in a fast bistable electronic system: a tunnel diode. We investigate the phenomenon in a higher frequency regime than that studied in previous experiments. Detailed measurements of the output signal are reported for two values of the frequency of the periodic signal: ${\mathit{f}}_{\mathit{s}}$=1 kHz and ${\mathit{f}}_ ...

Coulomb blockade of resonant tunneling
Physical Review B, 1994We have considered the influence of electromagnetic fluctuations on electron tunneling via one nondegenerate resonant level, the problem that is relevant for electron transport through quantum dots in the Coulomb blockade regime. We show that the overall effect of the fluctuations depends on whether the electron bands in external electrodes are empty ...

Resonant torus-assisted tunneling
Physical Review E, 2016We report a new type of dynamical tunneling, which is mediated by a resonant torus, i.e., a nonisolated periodic orbit. To elucidate the phenomenon, we take an open elliptic cavity and show that a pair of resonances localized on two classically disconnected tori tunnel through a resonant torus when they interact with each other. This so-called resonant

Coherence of resonant tunneling in heterostructures
Physical Review B, 1987A simple argument is put forward to substantiate the rule that either coherent resonant tunneling or sequential tunneling will occur according to whether the natural energy width for the former (in frequency units) is large compared to or small compared to the scattering frequency for an electron in the quantum-well two-dimensional subband based on the

Analysis of resonant-tunneling transport
Physical Review B, 1992We analyzed the properties of the two factors determining the resonant-tunneling transport: the one- dimensional carrier energy distribution factor, which monotonically decreases with energy and increases with temperature, and the transmission probability peak, which decreases with bias and temperature, and we determined a criterion for current ...

Two-channel resonant tunneling
Physical Review B, 1994We study the conductance of a tunneling junction with two resonant impurities. We show that when the distance between the impurities is of the order of the de Broglie wavelength of an electron in the contacts, the coupling of the impurity states via the continuum of states in the contacts becomes important.
