Potential, Ef, p and n at contacts¶ If we simply set the Ef at the contacts to -q*(applied bias voltage), we can prove that the electrostatic potential at a contact must then be equal to the applied voltage + the built-in potential of that contact with respect to an intrinsic reference. bodyguard et hitman https://jshefferlaw.com

WebAn electric field E forms between the positive ion cores in the n -type material and negative ion cores in the p -type material. This region is called the "depletion region" since the electric field quickly sweeps free carriers out, hence the region is depleted of free carriers. A "built-in" potential V bi is formed at the junction due to E. WebTo explain the origin of the surface states in metal semiconductor junctions, there had been two major attempts.
