← ScienceWithin tunneling diodes, which behavior results when the applied reverse voltage further depletes mobile carriers?
A)Current decreases following Fowler-Nordheim tunneling✓
B)Zener breakdown dominates charge transport
C)Increased forward bias voltage is mitigated
D)Thermionic emission generates additional charges
💡 Explanation
Fowler-Nordheim tunneling occurs because tunneling probability decreases exponentially with depletion width; therefore reverse voltage impedes tunneling, reducing current flow, rather than inducing Zener breakdown under different voltage polarity.
