Types of Semiconductor Materials | Intrinsic & Extrinsic Semiconductor | Engineering Funda

Semiconductor materials are classified into intrinsic and extrinsic types. Intrinsic semiconductors, like pure silicon, have lower conductivity due to a lack of free charge carriers. Extrinsic semiconductors, enhanced with impurities, exhibit higher conductivity. N-type and P-type materials are examples, with N-type containing extra electrons and P-type containing holes.
