Abstract

Hot electron diffusion coefficients in silicon at room temperature are theoretically studied by incorporating the band non-parabolicity and the effect of the diffusion current on the distribution function. Two models of intervalley scattering are considered: in one model, coupling with high-temperature intervalley phonons only is assumed; in the other, low-temperature intervalley phonons are also included. Both the models give practically identical results and the calculated values are found to agree closely with the experiment.
