← TechnologyWhich outcome occurs when excessive current surges in LEDs?
A)Filament thermal runaway and failure
B)Depletion region avalanche breakdown✓
C)Increased radiative recombination efficiency
D)Enhanced quantum dot light conversion
💡 Explanation
Avalanche breakdown occurs because extremely high current causes free carriers to generate more through impact ionization, therefore the depletion region fails, rather than increased emission, due to generated heat exceeding design parameters.
