Which consequence results when defects disrupt periodicity near graphene band gaps?

💡 Explanation

Increased electron-hole recombination occurs via increased scattering at defects. Defect-induced scattering enhances non-radiative transitions because the disrupting periodicity near band gaps introduces mid-gap states. Therefore, electron-hole recombination rate increases rather than suppressing effects occurring in pure crystals.
