Shot noise in negative-differential-conductance devices

چکیده
Shot noise: Fluctuations of the current flowing through a device that result from the discreteness of the charge carrier. Shot noise provides information on the charge carriers and the transport mechanism in the device. The shot noise measurements in semiconductor heterostructure devices shed light on how the devices operate, beyond information provided by the electrical conductance. The shot noise in a p-i-n photodiode with an embedded superlattice showed reduction of shot noise relative to the Poissonian noise (2eI) at low electric fields regardless of impinging photon energy.

Negative differential conductance and super-Poissonian shot noise in single-molecule magnet junctions
Molecular spintroinic device based on a single-molecule magnet is one of the ultimate goals of semiconductor nanofabrication technologies. It is thus necessary to understand the electron transport properties of a single-molecule magnet junction. Here we study the negative differential conductance and super-Poissonian shot noise properties of electron transport through a single-molecule magnet w...
متن کاملTransport through anisotropic magnetic molecules with partially ferromagnetic leads: Spin- charge conversion and negative differential conductance
We theoretically investigate inelastic transport through anisotropic magnetic molecules weakly coupled to one ferromagnetic and one nonmagnetic lead. We find that the current is suppressed over wide voltage ranges due to spin blockade. In this system, spin blockade is associated with successive spin flips of the molecular spin and depends on the anisotropy energy barrier. This leads to the appe...
متن کاملSimulation and Measurement of Shot Noise in Resonant Tunneling Structures
We present numerical simulations and measurements of shot noise in resonant tunneling structures. We show that when electron-electron interaction through Coulomb force and Pauli exclusion is properly taken into account, the main features of noise behavior of such devices can be correctly predicted. Electron-electron interaction is shown to be responsible for the suppression of shot noise in the...
متن کاملNonequilibrium spintronic transport through an artificial Kondo impurity: conductance, magnetoresistance, and shot noise.
We investigate the nonequilibrium transport properties of a quantum dot when spin flip processes compete with the formation of a Kondo resonance in the presence of ferromagnetic leads. Based upon the Anderson Hamiltonian in the strongly interacting limit, we predict a splitting of the differential conductance when the spin flip scattering amplitude is of the order of the Kondo temperature. We d...
متن کاملQuantum transport and noise in resonant tunneling diode using self-consistent Green function calculation
The fully self-consistent non-equilibrium Green function approach to the quantum transport is developed for the investigation of one-dimensional nano-scale devices. Numerical calculations performed for resonant tunneling diodes of different designs and at different temperatures show reasonable results for the potential and electron density profiles, as well as for the transmission coefficient a...
