← TechnologyWhich barrier height modulation enables a Schottky diode to switch?
A)Surface plasmon resonance coupling
B)Thermionic emission over barrier✓
C)Quantum mechanical electron tunneling
D)Frenkel defect mediated diffusion
💡 Explanation
A Schottky diode switches because thermionic emission current exponentially increases with reduced barrier height under forward bias, therefore current flows rather than due to tunneling, which is significantly weaker; surface plasmon resonance is irrelevant.
