  • Abstract
    The first successful fabrication of compositionally graded emitter InGa(As)P/GaAs HBTs is reported. It is found that the influence of recombination current in the emitter depletion layer on current gain characteristics by compositional grading is small. The recombination current in the InGa(As)P emitter layer is less than 1/10 that in an AlGaAs emitter layer grown at a 100°C higher temperature
