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. WebBipolar Transistor. The Bipolar Junction Transistor is a semiconductor device which can be used for switching or amplification. Unlike semiconductor diodes which are made up from two pieces of semiconductor material to form one simple pn-junction. The bipolar transistor uses one more layer of semiconductor material to produce a device with ...
