Variation of Fermi level with impurity concentration
- At low impurity concentration the impurity atoms do not interact with each other. Hence, the extrinsic carriers have their own discrete energy levels.
- With the increase in impurity concentration the interaction of the impurity atoms start and the Fermi level varies in the …
