← ScienceWhich outcome is observed regarding electron flow when two isolated metallic conductors are brought nanoscopically close?
A)Current flows without applied voltage.✓
B)Resistance approaches infinity asymptotically.
C)Resistance is independent of separation.
D)Thermionic emission current strongly dominates.
💡 Explanation
Current flows because quantum tunneling permits electrons to cross the classically forbidden gap; the mechanism is quantum-mechanical tunneling. Therefore, a non-zero current is observed, rather than infinite resistance without electron states within the gap.
