Shot noise suppression at one-dimensional hopping
We have carried out a preliminary analysis of shot noise at hopping, focusing on uniform one-dimensional ~1D! arrays of sites separated by N tunnel barriers. The results show that at low temperatures the low-frequency density of the shot noise varies from 1/N to 1 of the Schottky value, depending on the geometry, electron density, and Coulomb interaction strength. An interesting feature is v de...
متن کاملQuasi-Langevin method for shot noise calculation in single-electron tunneling
It is shown that quasi-Langevin method can be used for the calculation of the shot noise in correlated single-electron tunneling. We generalize the existing Fokker-Plank-type approach and show its equivalence to quasi-Langevin approach. The advantage of the quasi-Langevin method is a natural possibility to describe simultaneously the high (“quantum”) frequency range. 73.40.Gk; 72.70.+m Typeset ...
متن کاملLangevin approach for the shot noise calculation in single-electron tunneling
– The Langevin method for the calculation of the shot noise in correlated singleelectron tunneling is developed. Its equivalence to the existing Fokker-Plank-type approach is shown in the “orthodox” framework. The advantage of the Langevin method is a natural possibility to describe also the fluctuations in the high (“quantum”) frequency range. Correlated single-electron tunneling [1] has remai...
متن کاملShot Noise Suppression and Enhancement at 2D Hopping and in Single-Electron Arrays
We have carried out numerical simulations of shot noise at two-dimensional (2D) hopping and in 2D arrays of single-electron islands with and without random background charges. Such key transport characteristics as the average (dc) current 〈I〉, the single-particle density of states and the current fluctuation spectrum, have been calculated within a broad range of the applied electric field E and...
متن کاملTunneling in one-dimensional non-Luttinger electron liquid.
The conductance of a weakly interacting electron gas in the presense of a single scatterer is found at arbitrary strength of the scattering potential. At weak interaction, a simple renormalization group approach can be used instead of the standard bosonization procedure. Our technique allows to take into account the backscattering of electrons that leads to a non-Luttinger-liquid behavior of th...
