← ScienceWhich mechanism limits electron mobility in a silicon crystal?
A)Phonon scattering reduces average momentum✓
B)Zener tunneling causes band jumping
C)Doppler shift reduces carrier velocity
D)Compton scattering alters the wavefunction
💡 Explanation
Phonon scattering increases with temperature in silicon, thus the mechanism impeding electron drift is phonon scattering, because lattice vibrations disrupt the electron's path and reduce momentum transfer. Therefore, mobility decreases rather than increasing through other mechanisms.
