← ScienceWhich consequence results when crystalline silicon contains impurities forming mid-gap states?
A)Increased electron-hole recombination rate✓
B)Enhancement of phonon mean free path
C)Increased thermal conductivity sharply
D)Suppressed piezoelectricity immediately
💡 Explanation
Increased electron-hole recombination occurs because the Shockley-Read-Hall recombination mechanism allows electrons and holes to recombine energy levels introduced by impurities. Therefore, recombination rate increases, rather than phonon effects or material properties, which are less directly effected.
