It has poor conductivity
If certain amount of impurity atom is added to intrinsic semiconductor the resulting
semiconductor is Extrinsic or impure Semiconductor
It has good conductivity.
3.Define drift current? EC8252 ELECTRONIC DEVICES Question Bank
When an electric field is applied across the semiconductor, the holes move towards the
negative terminal of the battery and electron move towards the positive terminal of the battery.
This drift movement of charge carriers will result in a current termed as drift current.
