WebJun 6, 2024 · in n-type semiconductor, the Fermi level lies below the donor level (but, above the intrinsic level), so that the donors are ionised according to the Fermi-Dirac probability function. Analogous question would be: is Fermi level in p-type semiconductors above or below acceptor levels? solid-state-physics semiconductor … WebApr 7, 2024 · Fermi level – the highest energy level that an electron can occupy at absolute 0 temperature. From the energy level diagram of the n-type semiconductor, it’s clear …
