WebApr 10, 2024 · FETs are unipolar devices, which means they use only one type of charge carrier (electrons or holes) to control the current flow. The alternative to a unipolar device is a bipolar device. Unlike a unipolar device like an FET, a bipolar device such as a Bipolar Junction Transistor (BJT) uses both electrons and holes to control the current flow. WebThe term bipolar refers to the use of both holes and electrons as current carriers in the transistor structure. Figure 1: Basic BJT structure. The pn junction joining the base region and the emitter region is called the base-emitter junction. The pn junction joining the base region and the collector region is called the base-collector junction.
