← ScienceWhich outcome arises when a STM tip's electric field increases on a gold surface?
A)Increased electron quantum tunneling current✓
B)Suppressed thermionic electron emission
C)Decreased surface plasmon resonance energy
D)Enhanced diffusion barrier for adatoms
💡 Explanation
An increased electric field enhances **quantum tunneling** of electron wave functions, because the barrier width decreases exponentially, therefore increasing tunneling probability and measured current, rather than thermionic emission at higher temperatures.
