TLDR
In this paper, first-order time-dependent perturbation theory is used to derive expression for scattering rates in the presence of high electric fields, and it is suggested that the complicated retarded transport equations recently introduced into hot electron theory are not necessary to treat the intra-collisional field effect in the weak phonon coupling limit.Abstract:
First-order time-dependent perturbation theory is used to derive expression for scattering rates in the presence of high electric fields. Analysis in terms of Houston functions suggests that scattering rates are approximately field independent, but a more accurate treatment in terms of Airy functions shows that at sufficiently high fields, the resonant width of the scattering vertex is limited by the domain of integration, and a field dependent suppression of scattering occurs. This effect occurs first for small-wavevector phonons, and appreciable effects are expected for fields exceeding 104-105 V cm-1. It is also suggested that the complicated retarded transport equations recently introduced into hot electron theory are not necessary to treat the intra-collisional field effect in the weak phonon coupling limit at fields of interest in conventional semiconductor transport. At fields where suppression of scattering is significant, it is found that additional scattering into field-induced band tails is also important.read more

Theory of electron transport in small semiconductor devices using the Pauli master equation
TL;DR: In this paper, the Pauli master equation is used to simulate electron transport in very small electronic devices under steady-state conditions, and three one-dimensional examples solved by a simple Monte Carlo technique are finally presented.

A model study of field-dependent dynamical screening due to mobile electrons in submicron semiconductor devices
D Lowe,J R Barker +1 more
TL;DR: In this article, a generalised field-dependent screening function involving one-electron Wigner distributions and spectral functions is studied under various model approximations, where the field dependence of the screening arises from the action of a (constant) electric field within duration of a collision process (estimated from the uncertainty relations).

Nonequilibrium green function techniques applied to hot-electron quantum transport
TL;DR: In this paper, the difference between quantum ballistic transport and the conventional Boltzmann equation is pointed out, such as underlies resistance quantization in quantum point contacts (van Wees et al., 1988), and ballistic peaks observed in the distribution function of microstructures (Baranger and Wilkins, 1984).

Acceleration of Electrons in a Crystal Lattice
TL;DR: In this paper, it was shown that the wave vector increases linearly with the time within the bounds of a single Brillouin zone, and at the boundaries of the zones transitions to other zones may take place if the accelerating field is large enough.
