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 e€ects 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...

A quantum corrected energy-transport model for nanoscale semiconductor devices

An energy transport model coupled with the density gradient method as quantum mechanical corrections is proposed and numerically investigated. This new model is comprehensive in both physical and mathematical aspects. It is capable of describing hot electron transport as well as significant quantum mechanical effects for advanced devices with dimensions comparable to the de Broglie wave-length....

A Thermal-Fully Hydrodynamic Model for Semiconductor Devices and Applications to III–V HBT Simulation

Because of the interaction between self-heating and hot carriers effects, neither isothermal nor conventional macrothermal models are adequate for the simulation of state-of-the-art power devices; instead, a detailed electro-thermal model accounting for nonstationary transport, such as the Thermal-Fully Hydrodynamic (T-FH) model, is required. We apply a one-dimensional (1-D) implementation of s...
