摘要
The frequency dependence of the transverse optical mode in the long‐wavelength limit on the density of conduction electrons is calculated. This dependence is a consequence of the dielectric properties of the free electron gas which gives a change of the effective ion‐ion interaction. By putting the limiting frequency equal to zero one finds an equation for the ferroelectric Curie temperature. Copyright © 1969 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
