Unformatted text preview: diode, both n- and p- semiconductor are degenerate, meaning the Fermi level is inside the VB on the p- side and inside the CB on the n- side. At reverse bias, the electrons from the VB of the p- semiconductor tunnel to the CB of the n- semiconductor. At small forward bias, the electrons in the CB of n- semiconductor tunnel to the empty states in the VB of p- semiconductor. At some point, the overlap in energy...
