- W1570398310 abstract "${text{Ca}}_{1ensuremath{-}x}{text{Sr}}_{x}{text{VO}}_{3}$ is a Mott-Hubbard-type correlated electron system whose bandwidth can be varied by the V-O-V bond angle but the actual effect of bandwidth control on the electronic structure has been controversial in previous photoemission experiments. In this work, band dispersions and Fermi surfaces of ${text{SrVO}}_{3}$ and ${text{CaVO}}_{3}$ are studied by angle-resolved photoemission spectroscopy. Near the Fermi level $({E}_{F})$, three bands forming cylindrical Fermi surfaces derived from the three $text{V}text{ }3d$ ${t}_{2g}$ orbitals have been observed. The observed bandwidths for both compounds are almost half of those predicted by local-density approximation band-structure calculation, confirming mass renormalization caused by electron correlation. It has been clearly demonstrated that the width of the $d$ band in ${text{CaVO}}_{3}$ is narrower than that in ${text{SrVO}}_{3}$, qualitatively consistent with the result of band-structure calculation. Roles of the orthorhombic lattice distortion and electron correlation in the observed band narrowing are discussed." @default.
