We report a resonant inelastic x-ray scattering (RIXS) study of charge excitations in the electron-doped high-T(c) superconductor Nd1.85 Ce0.15 CuO4. The intraband and interband excitations across the Fermi energy are separated for the first time by tuning the experimental conditions properly to measure charge excitations at low energy. A dispersion relation with q-dependent width emerges clearly in the intraband excitation, while the intensity of the interband excitation is concentrated around 2 eV near the zone center. The experimental results are consistent with theoretical calculation of the RIXS spectra based on the Hubbard model.

“…The RIXS experiments were performed at BL11XU in SPring-8, where a specially designed inelastic x-ray scattering spectrometer was installed [4]. Using a Si (111) doublecrystal monochromator and a Si (400) channel-cut secondary monochromator, an incident energy resolution of about 220 meV was obtained.…”

We report a Cu K-edge resonant inelastic x-ray scattering (RIXS) study of high-Tc cuprates. Momentum-resolved charge excitations in the CuO2 plane are examined from parent Mott insulators to carrier-doped superconductors. The Mott gap excitation in undoped insulators is found to commonly show a larger dispersion along the [π, π] direction than the [π, 0] direction. On the other hand, the resonance condition displays material dependence. Upon hole doping, the dispersion of the Mott gap excitation becomes weaker and an intraband excitation appears as a continuum intensity below the gap at the same time. In the case of electron doping, the Mott gap excitation is prominent at the zone center and a dispersive intraband excitation is observed at finite momentum transfer.

“…Polarized SSXANES measurements were performed using a high-resolution X-ray spectrometer, especially designed for resonant X-ray scattering experiments and installed at the BL 11XU beamline of Spring-8 [49]. The monochromatized incident X-ray beam is produced using two Si(1 1 1) and two Si(4 0 0) crystals.…”
