Importance of fermi energy
Witryna1 kwi 2024 · The Fermi Level (with Fermi energy Ef) is the “surface” of this sea where electrons will not have enough energy to rise above the surface. It is the energy level … WitrynaThe In N, most stable in the 4+ charge state, has a low formation energy for Fermi levels near the VBM and may play a role as a compensating center in p-type InN. The indium interstitial (In i) and the nitrogen interstitial in its energetically preferable split-interstitial configuration (N i) act as donors.
