WebBipolar junction transistors are classified as minority carrier devices. Explain why. Reveal answer. Conduction through a BJT depends on charge carriers being “injected” into the base layer of the transistor, and these charge carriers are always the “minority” type with respect to the doping of the base. WebSemiconductor optical modulators are described that utilize bipolar junction transistor (BJT) structure within the optical modulator. The junctions within the BJT can be designed and biased to increase modulator efficiency and speed. An optical mode may be located in a selected region of the BJT structure to improve modulation efficiency. The BJT structure …
