Description

A complete data set for the phonon dispersion curves of PdTe2 along the [zeta00], [zetazeta0], and [00zeta] symmetry directions has been measured. A lattice-dynamical model consisting of axially symmetric Born--von Karman interactions to seventh-nearest neighbors together with shell-model contributions, introduced specifically to model dips in the low-energy optic branches in the vicinity of the GAMMA point, provides a reasonable fit to the measured dispersion curves. The results are discussed in relation to the known properties of PdTe2 and the dispersion data already available for related layered-structure compounds
