What is Degenerate semiconductor?

Degenerate semiconductor in the explanations

• At very high doping it can even enter a band (a degenerate semiconductor).

  Where is the Fermi level located in an n-type semiconductor?

• This is a degenerate semiconductor: the simple n × p = ni² relation no longer holds and the bandgap appears smaller (bandgap narrowing).
