question 49

Multiple Choice

The free-electron model of metals gives a good account of electrical conduction if

• A)the classical mean speed v_av is replaced by the Fermi speed u_F.
• B)the collisions between electrons and the lattice ions are interpreted in terms of the scattering of electron waves.
• C)the collisions between electrons and the lattice ions are interpreted in terms of the scattering of hard spheres.
• D)the classical mean speed v_av is retained in the model and the collisions between electrons and the lattice ions are interpreted in terms of the scattering of electron waves.
• E)the classical mean speed v_av is replaced by the Fermi speed u_F and the collisions between electrons and the lattice ions are interpreted in terms of the scattering of electron waves.
