“…The mechanism of mobility fluctuation was able to explain 1/f noise in thermo emf 27 and Hall voltage 28 of intrinsic and extrinsic semiconductors. An indirect support for phonon participation in 1/f noise came from the very low noise observed in near ballistic GaAs diodes 29 and short carbon nanotubes in the ballistic regime 30 , which was attributed to the near-absence of phonon scattering. Also, bulk and surface phonon number fluctuations have been invoked as explanation for the 1/f noise found in the light scattering by quartz crystal 31 and current fluctuations in STM 32 , respectively.…”

Two 1/f noise peaks were found in a carbon soot resistor at voltages characteristic of Kohn anomalies in graphite. The ratio of the electron-phonon coupling matrix elements at the anomalies calculated from the noise peak intensities is the same as the one obtained from the Raman frequencies. This demonstrates that the electron-phonon coupling is the microscopic source of 1/f noise in carbon soot. A new, very general formula was deduced for the frequency exponent, wherein nonlinearity and dispersion are the only ingredients. The interplay between nonlinearity and dispersion in this formula describes the sublinear-supralinear transitions experimentally observed at both anomalies in the voltage dependence of the frequency exponent. A quadratic dependence of the 1/f noise parameter on the matrix element is proposed and applied to explain the M-shape of the 1/f noise in graphene. We found that the frequency exponent mimics the dependence of the noise intensity in the whole voltage range, while both are the image of the graphite phonon spectrum. This implies that the source of nonlinearity is in the electron-phonon coupling which modulates the slope of the spectrum. It requires the presence of 1/f noise in the thermal noise background of the resistor till phonon frequencies.

“…Unfortunately, the data on noise measurements in these structures are scarce. 39 Due to a great progress in noise measurements in quantum ballistic conductors during the last ten years 7-10 ͑also see Ref. 3͒, we believe it would be now possible to measure the noise suppression effects in SCL ballistic conductors.…”

Electron transport in a self-consistent potential along a ballistic two-terminal conductor has been investigated. We have derived general formulas which describe the nonlinear current-voltage characteristics, differential conductance, and low-frequency current and voltage noise assuming an arbitrary distribution function and correlation properties of injected electrons. The analytical results have been obtained for a wide range of biases: from equilibrium to high values beyond the linear-response regime. The particular case of a threedimensional Fermi-Dirac injection has been analyzed. We show that the Coulomb correlations are manifested in the negative excess voltage noise, i.e., the voltage fluctuations under high-field transport conditions can be less than in equilibrium.

“…This is not the case, however, on what concerns the noise properties. The existing experimental data [13,14] are scarce and the theoretical calculations provide only some estimates valid in the space charge limited transport regime based on the theory of vacuum tubes [15] and of n + -i-n + ballistic diodes [16].…”

We present a semiclassical kinetic theory for the electronic transport and noise properties of ballistic n+ – n– n+ semiconductor nanodiodes. The theory is based on an exact solution of the Vlasov–Langevin kinetic equation self-consistently coupled to the Poisson equation, and takes into account the Pauli exclusion principle. The current–voltage characteristics calculated from the present theory perfectly agree with existing theoretical predictions. Concerning the noise properties, the theory offers the possibility of computing the current noise under all current regimes, thus overcoming the inherent limitations of existing theories.
