If no voltages are applied across … WebHere, holes are the majority charge carriers while electrons are the minority charge carriers. The figure below represents the circuit diagram of the p-n-p transistor: The emitter-base (V BE ) battery connects the p-type emitter which is forward biased whereas the collector-base (V BC ) battery connects the p-type collector which is reverse biased.

WebThe electrons in the base are called minority carriers because the base is doped p-type which would make holes the majority carrier in the base. Figure 8.3.1 Cross section of a planar NPN transistor ... NPN transistors consist of a layer of P-doped semiconductor (the “base”) sandwiched between two N-doped layers. ... WebFor instance, a PNP transistor functions by injecting holes into the base, where they are the minority carrier whereas an NPN transistor injects electrons into the base. Holes are a minority carrier when they are in an n-type material, and electrons are a minority carrier when they are in a p-type material.
