← ScienceWhich outcome results when doping disrupts a silicon crystal?
A)Reduction in mean free path✓
B)Increased phonon thermal conductivity
C)Augmented dielectric breakdown strength
D)Shift in the Debye temperature
💡 Explanation
Doping introduces impurities that scatter charge carriers and reduce the *mean free path*, because imperfections impede transport, therefore conductivity decreases rather than enhances, and the Debye temperature changes by a different order.
