SUMMARY

The primary distinction between ordinary and degenerate semiconductors lies in the positioning of the Fermi level (Ef) and the electronic density. In ordinary semiconductors, Ef is situated within the band gap with an electronic density of approximately 1018 cm-3. In contrast, degenerate semiconductors have Ef above the conduction band and exhibit a significantly higher electronic density of around 1022 cm-3, resulting in metallic-like conductivity and low resistivity. This behavior is described by the term "degenerate statistics."

ordinary Semiconductor: The Fermi level (Ef) is located within the gap, and its electronic density is around 10^18.

Degenerative one: Ef is located above the conduction band, and its electronic density is around 10^22. it conducts like a metal which has a low resistivity.
 
The correct term is:

"degenerate statistics"
