Dielectric function of SmS
Description
The zone-center longitudinal optical phonon of semiconducting SmS shows a 10% softening with respect to that of EuS. This result confirms the lattice-dynamical model prediction and provides first experimental evidence for the existence of an anomalous dipolar charge deformability of the Sm2+ ion in SmS. (author)
