| Abstract: | An analytical model for graded Al x Ga 0.52 x In 0.48 P/GaAs HBTs is established. The model has taken into account the effects of Al composition x on the temperature properties of HBTs. The results of theoretic calculation show that in the practical range of current density ( J c is around 10 3A/cm 2), the temperature stability of Al x Ga 0.52 x In 0.48 P/GaAs HBTs' current gain increases with x . When x =0.3, the maximum operable temperature can exceed 700 K. The reason for the reduction in current gain of HBTs at high temperature is also discussed. |
