Webb26 maj 2024 · Near to base B 2, a pn-junction is formed between a p-type emitter and the n-type silicon bar. The terminal of this junction is called emitter terminal (E). Since the device has three terminals and one pn-junction, for this region this is called as a Unijunction Transistor (UJT). The device has only pn-junction so it forms a diode. ariah agarwal boyfriendWebbPN Junction Capacitor Under thermal equilibrium, the PN junction does not draw any current But notice that a PN junction stores charge in the space charge region (transition region) Since the device is storing charge, it’s acting like a capacitor Positive charge is stored in the n-region, and negative charge is in the p-region: qNa xpo =qNd xno balance diagram怎么画

"WebbNear the junction, the N-type material electrons diffuse across the junction, combining with holes in P-type material. The region of the P-type material near the junction takes on a net negative charge because of the electrons attracted. Since electrons departed the N-type region, it takes on a localized positive charge. " - The pn junction is often referred to as the
