Question

In extrinsic P and N-type, semiconductor materials, the ratio of the impurity atoms to the pure semiconductor atoms is about(a) 1(b) 10⁻¹(c) 10⁻⁴(d) 10⁻⁷

Answer 1

I don't know of this question answer

Answer 2

Answer:

The ratio of the pure atoms to impure atoms in extrinsic semiconductors is (d) 10⁻⁷.

Explanation:

When pure or intrinsic semiconductors are doped with trivalent or pentavalent impurities then it results in the formation of n-type and p-type semiconductors.

This drastically affects the conduction of these semiconductors and provides free charge carriers to conduct electricity through the crystal.
