Thermal Conduction with Electron Flow/Ballistic Behavior

This chapter outlines two additional modeling approaches for thermal conduction inside a material. First, the electron-phonon hydrodynamic equations are considered for electron-phonon transport in MESFETs by including the electron flow from the source to the drain. Second, the electronic thermal conduction at nanoscale is modeled using a Monte Carlo method, which illustrates the effect of ballistic or semi-ballistic behavior of electrons on the temperature profiles between two parallel plates. These models can be used to replace the Fourier heat conduction and the two-temperature models discussed in Chapters 5 and 6 to account for the effects of electron flow and the ballistic behavior of heat carriers.
