Abstract
In this brief, a new method for extracting carrier mobility from the Monte Carlo device simulation is presented. Unlike the conventional method which is based on taking the time-average of the rate of change of momentum befor e and after the scattering, this method utilizes the spherical harmonic exp ansion of the carrier distribution function and an analytical expression fo r the relaxation time. The new method produces a much smoother result than the time-average method, particularly in low electric field regions.
