WebDec 8, 2024 · In a good HBT such as one using AlGaAs for an emitter and GaAs for a base, ΔE g ≈ 0.2eV. At room temperature k b T= 0.025eV and ΔE g / k b T = 8. Therefore ΔE g / k b T ≈ 3000. In a typical HBT, N e /P b ≈ 1/10. That is, the base is heavily doped compared to the emitter, minimizing base width modulation.
