The method is applied to the simulation of a 1-D BJT and to the computation of the collector current multiplication factor. A comparison with experimental data is presented.

The solution provides the energy distribution of electrons as a function of position in the entire device with a reasonable CPU time. We compare the average velocity and energy with results of the hydrody- namic model.
