Oxygen phonon branches in overdoped La$_{1.7}$Sr$_{0.3}$CuO$_4$

The dispersion of the Cu-O bond-stretching vibrations in overdoped La $_{1.7}$ Sr $_{0.3}$ CuO $_{4}$ (not superconducting) has been studied by high resolution inelastic neutron scattering. It was found that the doping-induced renormalization of the so-called breathing and the half-breathing modes is larger than in optimally doped La $_{1.85}$ Sr $_{0.15}$ CuO $_{4}$ . On the other hand, the phonon linewidths are generally smaller in the overdoped sample. Features observed in optimally doped La $_{1.85}$ Sr $_{0.15}$ CuO $_{4}$ which suggest a tendency towards charge stripe formation are absent in overdoped La $_{1.7}$ Sr $_{0.3}$ CuO $_{4}$ .
