The Boltzmann equation for transport in semiconductors is projected onto spherical harmonics such a way that the resultant balance equations coefficients of distribution function times generalized density states can be discretized over energy and real spaces by box integration. This ensures exact current continuity discrete equations. Spurious oscillations are suppressed stabilization based on maximum entropy dissipation principle avoiding H transformation. derived formulation used arbitrary...
