Abstract

The studies of ultra-violet photoemission spectroscopy and soft X-ray absorption spectroscopy of a perovskite-type 3d1 Mott-Hubbard system Ca1-xXrxVO3, which is metallic in the whole composition range (0<x<1), are reported. As we control electron-electron interaction of the system by changing the Sr concentration (x), we have observed a systematic change of the spectra, which clearly manifests how the single-particle density of states around Fermi level (EF) behaves near a Mott transition.
