Coupled device‐circuit simulation using energy‐momentum device models Available to Purchase

The use of energy‐momentum models for carrier transport is considered in the context of coupled device‐circuit simulation. We point out that certain computational methods for uncoupling the computations, successfully employed using drift‐diffusion models, can be slightly modified and made compatible with energy‐momentum models, assuming only a known or computable “momentum relaxation time”. By such means one can readily compare the results of transient simulations using energy‐momentum and drift‐diffusion models.
