definition:

semiconductor is partially an insulator and partially conductors

intrinsic semiconductors are pure materials with no intentional impurities

extrinsic semiconductors are intentionally doped with impurities to modify their electrical properties

-Semiconductors theory explains how the conductivity of material lies between that of a conductor an an insulator

Doping , a process of introducing impurities, allows us to control the conductivity and create p-type and n-type semiconductors
applying a voltage to a p-n junction allows for controlled current flow enabling functions like rectification(converting AC to DC) and amplifcation
