Question:medium

Temperature dependence of electron-hole mobility due to lattice scattering varies approximately as :

Show Hint

To remember which is which: High temperatures mean violent lattice shaking, which hinders movement (Phonon mobility drops, $T^{-3/2}$). High temperatures mean fast electrons that zip past charges too quickly to be pulled off course (Impurity mobility rises, $T^{3/2}$).
