Which mechanism leads to carrier avalanche in reverse-biased semiconductor junctions?

💡 Explanation

Increasing electric field accelerates carriers, and impact ionization increases exponentially when they attain sufficient kinetic energy hitting other atoms; this positive feedback causes avalanche rather than recombination, because the new free carriers continue cascade accelerating, therefore drastically increasing current flow.
