Question

define intrinsic and extrinsic semi conductors
​

Answer 1

Answer:

The pure form of the semiconductor is known as the intrinsic semiconductor and the semiconductor in which intentionally impurities is added for making it conductive is known as the extrinsic semiconductor.

Answer 2

⭐ $\sf\underline\red{ Intrinsic~~semiconductors}$ :- The semiconductors whose conductivity increases with rise in temperature are called intrinsic semiconductors.

❤ $\sf\underline\green{ Extrinsic~~semiconductors}$ :- The semiconductors whose conductivity increases by the addition of impurities are called extrinsic semiconductors.
