The heterojunction bipolar transistor (HBT) is a type of bipolar junction transistor (BJT) which uses differing semiconductor materials for the emitter and base regions, creating a heterojunction. The HBT improves on the BJT in that it can handle signals of very high frequencies, up to several hundred GHz. It is commonly used in modern ultrafast circuits, mostly radio frequency (RF) systems, and in applications requiring a high power efficiency, such as RF power amplifiers in c… WebGaAs 1.424 AlGaAs 1.758 Table 1: Bandgap energies for different semiconductors (1) HBT device structure Heavily doped n+ GaAs layers form low-resistance ohmic …
