Chemical potential and Fermi level

Click For Summary
SUMMARY

The discussion centers on the relationship between the Fermi level and the density of states (DOS) in metals. It concludes that while the Fermi level itself is not directly dependent on the DOS, the chemical potential, which is part of the Fermi-Dirac distribution, is influenced by the DOS. The Fermi energy level is determined by the total number of states up to the N-th electron in the system, indicating that the integrated total number of states and the energy level structure are crucial factors in this context.

PREREQUISITES
  • Understanding of Fermi-Dirac distribution
  • Knowledge of density of states (DOS) in solid-state physics
  • Familiarity with concepts of chemical potential
  • Basic principles of electron states in metals
NEXT STEPS
  • Research the role of chemical potential in Fermi-Dirac statistics
  • Study the mathematical formulation of density of states in metals
  • Explore the relationship between electron filling and Fermi energy levels
  • Investigate the effects of temperature on Fermi level and DOS
USEFUL FOR

Physicists, materials scientists, and students studying solid-state physics who are interested in the electronic properties of metals and the implications of Fermi level and density of states on material behavior.

TL;DR
My question is aimed to know where fermi level depends on Density of states or not
Does fermi level (in metals) depend on the density of states? I am asking this because from fermi-dirac distribution it seems like that fermi level is non-dependent of DOS, but there is chemical potential in fermi-dirac distribution, which is said to be dependent of DOS.

Say there are 2N electrons in the system, I think N-th number of states counting from the ground state would become Fermi energy level. In that sense not density but integrated total number of states and energy levels structure would matter.
