Abstract

We report the experimental determination of acoustic and optical phonon curves of 2H-TaSe2(001) by means of He scattering. The Rayleigh modes at 140 K appear to be well localized below the bulk transverse acoustic band at the zone boundary. The data, analysed by a dispersive-linear chain model, indicate a substantial change of interactions in the Ta sheet of the topmost layer
