On the nonlinear modeling of shot noise.
We introduced a nonlinear shot-noise model, a natural generalization of the "classic" shot-noise model, which differs markedly from the existing linear shot-noise models. This model produces a wide spectrum of stationary noise processes. Because of its intrinsic nonlinearity, the model's resulting noise processes are capable of displaying a rich variety of both amplitudal and temporal statistic...
متن کاملOn the ‘Anomalous’ Resurgence of Shot Noise in Long Conductors
There has been renewed interest in the physics of the so-called ‘crossover’ for current fluctuations in mesoscopic conductors, most recently involving the possibility of its appearance in the passage to the macroscopic limit. Shot noise is normally absent from solid-state conductors in the large, and its anomalous resurgence there has been ascribed to a rich interplay of drift, diffusion, and C...
متن کاملShot noise at hopping via two sites
Shot noise in mesoscopic structures has been the subject of thorough studies in the recent past. In particular, a theory of shot noise at tunneling of single electrons correlated due to Coulomb blockade effects has been well developed and verified experimentally. Recently, attempts have been made to extend this theory to hopping transport, which can be formally considered as a special case of c...
متن کاملShot-noise suppression at two-dimensional hopping
We have used Monte Carlo simulation to calculate the shot-noise intensity SI(v) at ~two-dimensional! hopping using two models: a slanted lattice of localized sites with equal energies and a set of localized sites with random positions and energies. For wide samples we have found a similar dependence of the Fano factor F[SI(0)/2eI on the sample length L: F}L 2a where a50.8560.02 and a50.8560.07 ...
متن کاملShot 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...
