Which mechanism creates electronic blocking when a voltage is applied?

💡 Explanation

A Schottky barrier creates a depletion region, because band bending occurs near the metal-semiconductor junction, pinning the Fermi level. This presents a potential barrier blocking electron flow rather than increasing scattering or electron energy; therefore it permits current rectification.
