← ScienceWhich consequence results when impurities distort a semiconductor's periodicity?
A)Modulated chemical reactivity
B)Increased electron-hole recombination✓
C)Increased magnetic domain alignment
D)Enhanced phonon scattering
💡 Explanation
Increased electron-hole recombination happens when impurities cause disruptions, because deviations introduce energy states within the band gap via **Impurity Scattering**. Therefore, carriers are more easily trapped and recombine rather than remaining free; increasing recombination exceeds other effects.
