← ScienceWhich effect occurs when mismatched work functions touch within ohmic contacts?
A)Formation of Schottky barrier✓
B)Ideal unrestricted current flow
C)Increased electron-hole recombination
D)Augmented majority carrier concentration
💡 Explanation
A depletion region occurs near metal-semiconductor junctions because of Fermi level alignment, forming a Schottky Barrier. Therefore, band bending appears because of different properties, rather than free unrestricted flow at contact.
