Numerical Simulation of the Smooth Quantum Hydrodynamic Model for Semiconductor Devices
An extension of the classical hydrodynamic model for semiconductor devices to include quantum transport eects is reviewed. This ``smooth'' quantum hydrodynamic (QHD) model is derived speci®cally to handle in a mathematically rigorous way the discontinuities in the classical potential energy which occur at heterojunction barriers in quantum semiconductor devices. A conservative upwind discretiz...
متن کاملSmooth Quantum Hydrodynamic model vs. NEMO Simulation of Resonant Tunneling Diodes
The smooth quantum hydrodynamic model is an extension of the classical hydrodynamic model for semiconductor devices which can handle in a mathematically rigorous way the discontinuities in the classical potential energy which occur at heterojunction barriers in quantum semiconductor devices. Smooth QHD model simulations of the current-voltage curves of resonant tunneling diodes are presented wh...
متن کاملNumerical Simualtion of Nanoscale Semiconductor Devices
Device modeling of novel semiconductor devices requires adapted physical models which include quantum mechanical effects. The quantum hydrodynamic as well as the quantum drift diffusion model offers effective possibilities for the simulation of nanoscale devices, particularly if tunneling processes appear. The models can be implemented effectively in conventional device simulation systems.
متن کاملFinding Electrostatics modes in Metal Thin Films by using of Quantum Hydrodynamic Model
In this paper, by using a quantum hydrodynamic plasma model which incorporates the important quantum statistical pressure and electron diffraction force, we present the corrected plasmon dispersion relation for graphene which includes a k quantum term arising from the collective electron density wave interference effects (which is integer and constant and k is wave vector). The longitudinal ...

With the advancement of nanoscale semiconductor technology,semiconductor optical amplifiers are used to amplify and process all-optical signals. Inthis paper, with the aim of calculating the gain of quantum dot semiconductor opticalamplifier (QD-SOA), two groups of rate equations and the optical signal propagatingequation are used in the active layer of the device. For t...
