A hydrodynamical model for holes in silicon semiconductors: The case of non-parabolic warped bands

An asymptotic solution for the SHE equations describing the charge transport in semiconductors .

In the framework of charge transport in semiconductors, a technique widely used in order to find approximate solutions of the Boltzmann transport equation (BTE) is based on a spherical harmonics expansion (SHE) of the distribution function (Rahmat, White and Antoniadis, 1996; Vecchi and Rudan, 1998; Ventura, Gnudi and Baccarani, 1995; Liotta and Struchtrup, 2000). Recently an asymptotic solutio...

Simulation of Submicron Silicon Diodes With a Non-Parabolic Hydrodynamical Model Based on the Maximum Entropy Principle

The dispersion relation for magneto-plasma waves in multivalley semiconductors

The dispersion relation for plasma waves. propagating at an arbitrary angle to an external magnetic field, has been calculated on the basis of the Vlasov equation. The energy bands are assumed to be multivalley, non-parabolic and non-spherical. The case of strong degeneracy of the electron gas has been analysed.

Numerical Modeling of a Fredkin gate using photonic-crystal-based nonlinear effects around the 1550 nm telecommunication wavelength

In this paper, a Fredkin gate using photonic-crystal around the 1550 nm telecommunication wavelength is modelled. The proposed structure has a compact footprint compared with previous works of research groups. The proposed structure is based on air holes on silicon substrate. Silicon substrate and air holes have 466 nm and 177 nm radius, respectively. For analyse of the structure Finite-Differe...

High Field Mobility and Diffusivity of Electron Gas in Silicon Devices

Abstract. In this paper the Boltzmann equation describing the carrier transport in a semiconductor is considered. A modified Chapman-Enskog method is used, in order to find approximate solutions in the weakly non-homogeneous case. These solutions allow to calculate the mobility and diffusion coefficients as function of the electric field. The integral-differential equations derived by the above...
