Question

the base of a transistor is doped​

Answer 1

Answer: In most transistors, emitter is heavily doped. Its job is to emit or inject electrons into the base. These bases are lightly doped and very thin, it passes most of the emitter-injected electrons on to the collector.

Answer 2

Answer:

The base of a transistor is doped​ lightly so that the maximum charge carrier can reach the collector.

Explanation:

• A vast number of charge carriers are released by the emitter of a transistor, most of which are captured by the collector and only a small percentage (approximately 5%) recombine in the base.
• As a result, the base is extremely weakly doped, the emitter is very extensively doped, and the collector has a lower doping concentration than the emitter.

• To allow the maximum number of charge carriers to reach the collector, the transistor's base has been gently doped.

• Through the base, electrons travel from the emitter to the collecting region.

• The base will become a barrier for electrons or holes if it is thick and extensively doped, which will prevent electron flow and, consequently, current flow. Consequently, a transistor's base has slight doping.
