← ScienceWhich consequence results when the excitation wavelength increases within a semiconductor's absorption band?
A)Photocurrent generation decreases exponentially✓
B)Increased electron-hole recombination emission
C)Quantum efficiency experiences substantial improvement
D)Decreased material surface penetration depth
💡 Explanation
When excitation wavelength increases within the absorption band, photon energy decreases; therefore, fewer electron-hole pairs are generated, causing photocurrent generation to decrease through reduced *photoelectric effect*, rather than increased carrier recombination or surface concentration.
