Journal ArticleDOI
The quantum hydrodynamic model for semiconductor devices
TL;DR: The full three-dimensional quantum hydrodynamic (QHD) model is derived for the first time by a moment expansion of the Wigner–Boltzmann equation.
Journal ArticleDOI
Smooth quantum potential for the hydrodynamic model
TL;DR: By cancelling the leading singularity in the classical potential at a barrier and leaving a residual smooth effective potential (with a lower potential height) in the barrier region, the effective stress tensor makes the barrier partially transparent to the particle flow and provides the mechanism for particle tunneling in the QHD model.
Journal ArticleDOI
Numerical methods for the hydrodynamic device model: subsonic flow
TL;DR: An introduction to the hydrodynamic model for semiconductor devices is presented and arguments for existence of solutions and convergence of numerical methods are given for the case of subsonic electron flow.
Journal ArticleDOI
Numerical simulation of a steady-state electron shock wave in a submicrometer semiconductor device
TL;DR: In this article, the first numerical simulations of a steady-state electron shock wave in a semiconductor device were presented, using the hydrodynamic model, which consists of a set of nonlinear conservation laws for particle number, momentum, and energy coupled to Poisson's equation for the electric potential.

The dynamics of bubble growth for Rayleigh-Taylor unstable interfaces
TL;DR: In this paper, a statistical model is analyzed for the growth of bubbles in a Rayleigh-Taylor unstable interface, compared to solutions of the full Euler equations for compressible two phase flow, using numerical solutions based on the method of front tracking.
