← ScienceWhich outcome accompanies increased temperature impacting silicon photodiode current?
A)Increased reverse saturation current noise✓
B)Decreased quantum efficiency stability
C)Enhanced electron-hole recombination lifetime
D)Reduced band gap modulation response
💡 Explanation
Increased temperature introduces greater atomic vibrational energy in the crystal lattice, increasing phonon scattering events; this increases reverse saturation current, because more electrons gain enough energy to overcome the potential barrier, therefore noise increases rather than decreases in device performance.
