Question

an extremely pure semi conductor is called​

Answer 1

Answer:

An intrinsic(pure) semiconductor, also called an undoped semiconductor or i-type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the material itself instead of the amount of impurities.

Answer 2

Explanation:

Semiconductors are materials that have properties in between normal conductors (materials that allow electric current to pass, e.g. aluminium) and insulators (which block electric current, e.g. sulphur). ... They are also called "undoped semiconductors" or "i-type semiconductors".
