Simulation of Gunn oscillations with a non‐parabolic hydrodynamical model based on the maximum entropy principle Available to Purchase

On the basis of the maximum entropy principle, seeks to formulate a hydrodynamical model for electron transport in GaAs semiconductors, which is free of any fitting parameter.

The model considers the conduction band to be described by the Kane dispersion relation and includes both Γ and L valleys. Takes into account electron‐non‐polar optical phonon, electron‐polar optical phonon and electro‐acoustic phonon scattering.

The set of balance equation of the model forms a quasilinear hyperbolic system and for its numerical integration a recent high‐order shock‐capturing central differencing scheme has been employed.

Presents the results of simulations of n⁺ ‐n‐n⁺ GaAs diode and Gunn oscillator.
