TLDR
In this paper, the authors solved the Langevin Boltzmann equation for the first time and showed that the contribution of hot electrons in a velocity saturation region is negligible, which corroborates previous findings based on the less accurate impedance field method.
Abstract
The open question whether excess noise is due to hot electrons or not is addressed for the first time by solving the full Langevin Boltzmann equation. Not only the bulk case is analyzed but also devices. In contrast to the well-known Monte Carlo method this new approach allows the investigation of the spatial origin of the terminal current noise. It is shown, that excess noise in devices is mainly due to cold or warm electrons. The contribution of hot electrons in a velocity saturation region is found to be negligible. This corroborates previous findings based on the less accurate impedance field method.

Numerical Simulation of RF Noise in Si Devices

TL;DR: The workhorse of today's TCAD is the drift-diffusion (DD) model, which in the special formulation of the impedance field method has been used for a long time for noise calculation, but there has been much debate over its noise source as discussed by the authors.

TL;DR: In this article, the impact of hot carrier induced interface damage and its spatial location on RF noise in deep sub-micrometer NMOSFETs was studied and it was demonstrated that the presence of interface states at source side shows much greater impact on the degradation of NFmin and Rn.
