← ScienceWhich risk increases when a photodiode's manufacturing process drastically reduces the width of the energy band gap?
A)Increased reverse leakage current failure✓
B)Reduced electron-hole recombination blockage
C)Faster response conduction saturation
D)Lower quantum efficiency amplification error
💡 Explanation
Increased reverse leakage occurs because reducing the band gap lowers the energy needed for electrons to jump to the conduction band via thermal excitation; therefore more current flows, rather than the generation of electron-hole pairs dominates.
