Phonon dispersion in 1-layer cuprate HgBa2CuO4+d

Abstract

We investigate the low energy acoustical and optical modes in $\mathrm{HgB}{\mathrm{a}}_2\mathrm{Cu}{\mathrm{O}}_{4+\delta }$ using inelastic x-ray scattering (IXS). The experimental phonon dispersion and the dynamical structure factor are compared with an atomic shell model, and the set of the atomic potentials obtained are discussed. Our results are also compared with those obtained by Raman spectroscopy and with density-of-state data measured by inelastic neutron scattering.
