Are transistors semiconductors?

Hint: Semiconductors are devices which have conductivity less than metals but more than insulators. Their conductivity increases with increase in temperature. There are two types of semiconductors; p-type and n-type. Transistors are used as switches for electric signals and electric power and are also used as amplifiers. Transistors are made by combining three parts.

Complete answer:
Semiconductors are those elements which have electrical conductivity more than the insulators but less than conductors. There are two types of semiconductors; p-type and n-type semiconductors.
In p-type semiconductors, movement of holes conducts electricity while in n-type semiconductors movement of electrons conduct electricity.
Transistors are made by combining terminals; collector, base, emitter.
These terminals are combined together in a transistor to amplify electronic signals, act as a switch for electrical signals or electronic power.
The three terminals of the transistor are semiconductor and hence a transistor is also a semiconductor.
The different types of transistors are P-N-P transistor, where a n-type semiconductor is placed between two p-type semiconductor
N-P-N transistor -where a p-type semiconductor is placed between two n-type semiconductors.
Therefore, transistors are also semiconductor devices because they are made by combining three semiconductors.



Note: Transistors are the building blocks of all electronic devices. Out of the collector, base and emitter; the collector is the largest part and the base is the smallest part. P-type semiconductors are made by doping intrinsic semiconductors with elements which have shortage of electrons while the n-type semiconductors are made by doping intrinsic semiconductors with elements which have extra electrons.
