← ScienceWhich outcome occurs when anisotropic thermal expansion fractures crystalline silicon?
A)Phonon scattering dominates conduction✓
B)Electron mobility increases drastically
C)Ferromagnetic domains spontaneously align
D)Superconductivity emerges instantaneously
💡 Explanation
A fractured crystal allows heat transfer via phonon scattering because phonon transport depends on crystal lattice order breakdown during expansion, therefore phonon scattering will dominate the conduction rather than electron mobility increasing or enabling collective quantum phenomena.
