The contribution of lattice vibrations to the dielectric function 
(q,ω) of metals
H Hinkelmann
Show affiliationsThe response of the system of conduction electrons to the lattice vibrations is considered up to the second order in the ion displacements. From this the author derives relations between the complex dielectric function epsilon (q, omega ) of a metal and the dynamical structure factor S(q, omega ) of its ions. epsilon (q, omega ) shows resonance behaviour at the phonon frequencies. The order of magnitude of the vibration contribution to epsilon (q, omega ) depends on the material considered.
