Abstract

A novel numerical model for AlGaAs/GaAs heterojunction bipolar transistors (HBTs) is proposed in which the transport of electron energy is included using hydrodynamic equations derived from the Boltzmann equation. This model can analyze nonequilibrium transport effects such as velocity overshoot, which the conventional static model cannot handle. It is shown that the importance of energy transport effects arises from the fact that the average electron energy deviates largely from the field-determined one. The velocity overshoot can occur in a graded-gap base and a collector depletion region, resulting in a much higher cutoff frequency than that predicted by the conventional model.
