Abstract :
Numerical simulations of an AlGaAs/GaAs heterojunction bipolar transistor are performed by using an energy transport model. It is found that the energy relaxation time is an important parameter to determine the device performance. A longer energy relaxation time is desirable to achieve a higher cutoff frequency.
