Abstract
We report on studies of the structure and dynamics of the (0Â 0Â 1) surface of single crystal LiCu2O2, investigated by He beam scattering at room temperature, and with lattice-dynamical models. The best fit surface corrugation to measured diffraction patterns shows that the surface termination is exclusively a Li1+Cu2+O2â plane. Lattice dynamics fits to inelastic He scattering spectra reveal the presence of two low-lying surface phonon modes, identified with the motion of Cu2+, Li1+ surface ions normal to the surface.
