(A) Thin and heavily
(B) Thick and lightly
(C) Thick and heavily
(D) Thin and lightly
The Base of a transistor is thin and lightly doped. A thin layer of n-type semiconductor or P-type semiconductor sandwiched between two P-type semiconductors or two N-type semiconductors creates a junction transistor. A thin layer of P-type semiconductors is sandwiched between two N-type semiconductors to create an NPN transistor.

Types of Transistor
A thin layer of N-type semiconductors is sandwiched between two P-type semiconductors to create a PNP transistor. Transistor has three main regions that are Base, Emitter, and Collector.
Emitter (E)
- It supplies the vast bulk of the charge carriers that allow the transistor’s current to flow.
- The emitter semiconductor is hence severely doped.
Base (B)
- It allows for proper communication between the emitter and the collector.
- The basis area is minimally doped and thin.
Collector (C)
- The collector’s primary function is to gather the majority of charge carriers from the emitter.
- The collection region is somewhat dopped and greater in size than the other two parts.
Summary:
The Base of a transistor is _________ doped? (A) Thin and heavily (B) Thick and lightly (C) Thick and heavily (D) Thin and lightly
Transistors have narrow, lightly doped bases. A junction transistor is formed by sandwiching two P-type semiconductors or two N-type semiconductors with a thin layer of n-type semiconductor, a thin layer of P-type semiconductor, or both.
