← ScienceWhich risk increases dramatically when semiconductor crystal lattice periodicity fails?
A)Reduced electron-hole recombination lifetime
B)Increased phonon scattering resistance
C)Uncontrolled electron avalanche multiplication✓
D)Enhanced plasmon resonance frequency
💡 Explanation
Uncontrolled electron avalanche multiplication arises because, when lattice periodicity fails, electron mobility dramatically increases due to reduced scattering events. Therefore, the electric field required for avalanche breakdown decreases rather than other effects related to electron behavior or phonon scattering.
