CoachDegenerate semiconductors have a high concentration of charge carriers due to doping, while non-degenerate semiconductors have a low concentration. Degenerate semiconductors exhibit metallic-like conductivity and Fermi level is inside the conduction or valence band, while non-degenerate semiconductors have a well-defined band gap and behave as insulators at low temperatures.

What is the difference between phosphorus doped and gallium doped semiconductors?
Phosphorus-doped semiconductors are n-type, meaning they have excess electrons, while gallium-doped semiconductors are p-type, meaning they have excess holes. This difference in conductivity types affects how the semiconductors interact with electricity and other components in electronic devices.
A substance that will conduct electricity only under certain conditions?
Semiconductor materials like silicon can conduct electricity under certain conditions, such as by adding impurities to create n-type or p-type semiconductors. These materials have a conductivity intermediate between that of conductors and insulators, allowing them to be used in electronic devices like transistors.
Are part time band leaders semiconductors?
No, part-time band leaders are not semiconductors. Semiconductors are materials that have properties between conductors and insulators and are commonly used in electronic devices. A part-time band leader is a person who leads a musical band on a part-time basis.
How are materials classified on the basis of resistivity?
Materials can be classified based on their resistivity as conductors, semiconductors, or insulators. Conductors have low resistivity, allowing electric current to flow easily. Semiconductors have resistivity in between conductors and insulators, and their conductivity can be controlled. Insulators have high resistivity and do not allow electric current to flow easily.
What do metalloid and semiconductor have in common?
Metalloids and semiconductors have similar properties due to their intermediate characteristics between metals and nonmetals. Both can conduct electricity to some extent, with metalloids having properties of both conductors and insulators, while semiconductors are used in electronic devices due to their ability to control the flow of current.
