Question

define intrinsic and extrinsic semiconductors (based on diploma subject electrical engineering materials)​

Answer 1

Answer:

A semiconductor in extremely pure form is known as intrinsic semiconductor. By adding some amount of impurity atoms to pure/intrinsic semiconductors, we can change it's conductivity/characteristics. The process is called doping and this impurity added semiconductors are called extrinsic semiconductors .

Answer 2

Answer:

Hey Buddy here's ur answer

The pure form of the semiconductor is known as the intrinsic semiconductor.

The semiconductor in which intentionally impurities is added for making it conductive is known as the extrinsic semiconductor.
