SUMMARY
The discussion clarifies that semiconductors do not possess a traditional Fermi surface as found in metals. Instead, the concept of the Fermi level is more applicable, representing the highest occupied energy states within the valence band of a semiconductor. The distinction lies in the fact that semiconductors have a band gap, which prevents the formation of a continuous Fermi surface. For a deeper understanding, the Wikipedia article on Fermi levels and band structure is recommended.
