← ScienceWhich tunneling consequence explains semiconductor diode reverse current?
A)Electrons breach forbidden energy gap✓
B)Phonons increase junction temperature
C)Holes exploit surface recombination
D)Atoms overcome lattice vibrations
💡 Explanation
Electrons tunnel through energy gaps due to high electric fields. The Zener effect causes reverse current, because electrons can overcome the band gap, therefore current flows, rather than blocking under normal reverse bias.
