What Are Intrinsic Semiconductors?

Intrinsic semiconductors are pure semiconductors that are completely free of impurities and have no lattice defects. They are called intrinsic semiconductors. But actual semiconductors cannot be absolutely pure. Such semiconductors are called impurity semiconductors. An intrinsic semiconductor generally refers to a pure semiconductor whose conductivity is mainly determined by the intrinsic excitation of the material. More generally, a semiconductor that is completely pure and free of impurities is called an intrinsic semiconductor or an I-type semiconductor. It mainly represents the single crystal structure of silicon and germanium.

Intrinsic semiconductor

An intrinsic semiconductor is a pure semiconductor that contains absolutely no impurities and no lattice defects. Actual semiconductors cannot be absolutely pure. Intrinsic semiconductors are generally pure semiconductors that guide electricity to be determined primarily by the intrinsic excitation of the material.

There are two types of intrinsic semiconductors.

, impurity semiconductor: n-type, p-type;

, intrinsic semiconductor, also known as pure semiconductor
