The emitter of a BJT is heavily doped so that it can inject a large number of majority charge carriers into the base. The base is very thin and lightly doped, which allows most of the injected carriers to reach the collector. This structure enables a relatively small base current to control a much larger collector current, providing transistor amplification.
The emitter in a transistor is ______ doped.
