Fermi Level -- clarification needed 1. The problem statement, all variables and given/known data Revered Members, Can i know what is meant by fermi level? I googled this, but i could not understand. One site says Fermi level as top of collection of electron energy levels at absolute zero. 2. Relevant equations 3. The attempt at a solution As far as my knowledge I know electron energy levels as K, L,M, N etc with energy values -13.6eV, -3.4eV etc. Top of collection means, is it O eV?
