SUMMARY
Zener tunneling phenomena involve the tunneling of electrons from the conduction band of the n-type region into the valence band of the p-type region, particularly in tunnel diodes under small bias conditions. The process is characterized by the non-local generation of carriers, as the Fermi energy in a tunnel diode does not reside within the band-gap. This understanding is crucial for analyzing the behavior of carriers during tunneling events. The discussion clarifies that the generation of holes and electrons is a direct consequence of this tunneling mechanism.
