Question

A doped intrinsic semiconductor is called a/an ________ semiconductor.

• A. intrinsic
• B. extrinsic
• C. doped semiconductor
• D. active semiconductor

Answer 1

The correct option is B extrinsic

A pure semiconductor or semiconductor with no impurities is called intrinsic semiconductor. When a pure semiconductor is doped with an impurity, the process is called doping, due to increased conductivity of an extrinsic semiconductor. Such a semiconductor is called extrinsic semiconductor.
