← ScienceWhich mechanism impacts electron mobility when impurities distort a crystal lattice?
A)Decreased mean free path length✓
B)Increased phonon resonant frequency
C)Enhanced electron-hole recombination rate
D)Increased dielectric breakdown voltage
💡 Explanation
Decreased mean free path length dominates electron behavior in distorted lattices because the distorted lattice introduces scattering centers, limiting electron travel via phonon scattering, therefore reducing mobility, rather than affecting phonon resonant frequency at such modest distortion levels.
