Which consequence results when crystal lattice dislocation-induced band gaps shift?

💡 Explanation

Higher defect densities in semiconductors can cause dislocations which create localized energy states and modify the band gap structure. This increases Schockley-Read-Hall recombination, reducing carrier lifetimes, because electrons and holes can now recombine via these mid-gap states rather than the band-to-band transition.
