摘要：
A velocity overshoot model of ultra-thin-base SiGe and SiGeC HBT is obtained. By deriving the Boltzmann electron temperature equation, 3000K maxima near the collector-base junction of temperatures are found. Velocities distribution solutions considering velocity overshoot are achieved. Conclusions are that different germanium content percentage decides the maxima of overshoot velocities and base overshoot is observed. SiGeC HBT possesses approximately the same velocities as in SiGe HBT.
