Momentum-dependent resonant inelastic X-ray scattering at the Si K edge of 3C-SiC: A theoretical study on a relation between spectra and valence band dispersion
Yunori Nisikawa, Muneharu Ibuki, Manabu Usuda
We theoretically demonstrate that a resonant inelastic x-ray scattering (RIXS) with a sizable momentum transfer can be utilized to study valence band dispersion for broad band mate…
Anisotropy of Resonant Inelastic X-Ray Scattering at the K Edge of Si:Theoretical Analysis
Yunori Nisikawa, Manabu Usuda, Jun-ichi Igarashi
We investigate theoretically the resonant inelastic x-ray scattering (RIXS) at the edge of Si on the basis of an ab initio calculation. We calculate the RIXS spectra with syste…
Resonant Inelastic X-Ray Scattering at the K Edge of Ge
Yunori Nisikawa, Manabu Usuda, Jun-ichi Igarashi +2
We study the resonant inelastic x-ray scattering (RIXS) at the edge of Ge. We measure RIXS spectra with systematically varying momenta in the final state. The spectra are a mea…
All-electron GW calculation based on the LAPW method: application to wurtzite ZnO
Manabu Usuda, Noriaki Hamada, Takao Kotani +1
We present a new, all-electron implementation of the GW approximation and apply it to wurtzite ZnO. Eigenfunctions computed in the local-density approximation (LDA) by the full-pot…
