The Fermi level changes as the solid is … TīmeklisIf the energy level spectrum is a continuum (or almost a continuum) the three levels coincide. In a many-body approach, the Fermi level is the energy necessary for adding or subtracting a particle from the system. This definition encompasses the non-interacting case. Like all energy states, the Fermi level is measured from the …
