← ScienceWhich risk increases significantly when temperature causes increased phonon activity in crystalline silicon?
A)Reduced electron mobility performance✓
B)Increased secondary electron emission
C)Enhanced X-ray diffraction contrast
D)Increased crystal lattice periodicity
💡 Explanation
Rising temperatures enhance phonon activity, which causes electron scattering via the electron-phonon interaction because the increased atomic vibrations disrupt electron flow through the material; therefore, electron mobility drops, rather than X-ray or lattice increases.
