Which consequence results when excess electron flow overwhelms a photodiode?

A)Increased thermal runaway resistance
B)Electron avalanche multiplication initiates
C)Enhanced dopant barrier resistivity
D)Lowered quantum mechanical confinement

💡 Explanation

Electron flow leading to avalanche occurs because increased bias accelerates electrons, initiating impact ionization; therefore, carrier multiplication increases, rather than confinement changes, different resistance, or thermal stability, which affect other modes, like dark current.
