← ScienceWhich consequence results when high energy photons illuminate a semiconductor's surface?
A)Increased electron-hole pair recombination rate
B)Decreased depletion region width forms
C)Enhanced quantum dot electron tunneling✓
D)Reduced atomic nuclei binding energy
💡 Explanation
Illumination injects carriers. Enhanced quantum dot electron tunneling occurs because photoexcitation raises electron energy levels enabling electron wave function overlap therefore increasing the probability of their passage because thickness decreases when excited, rather than changing recombination behavior.
