← ScienceWhich consequence results when bias induces interband tunneling?
A)Zener diode conducts electricity✓
B)Ohmic resistance decreases linearly
C)Capacitance value reaches zero
D)Material becomes a superconductor
💡 Explanation
The Zener diode conducts because the large electric field enables electrons to tunnel across the band gap, called Zener tunneling. Therefore, current drastically increases, rather than linearly decreasing Ohmic resistance which lacks the tunneling requirement.
