Abstract

The energy band structure of a quasi one-dimensional cuprate SrCuO₂ is studied by angle-resolved photoemissionspectroscopy and the linear augmented-plane-wave band structure calculationwithin local density approximation. It was found that the band structure has strongly one-dimensional nature with a finite dispersion along the Cu-O chains.The calculated band structure of SrCuO₂ is in good agreement with theangle-resolved photoemission result except for the region near the Fermi level.
