We have performed an angle-resolved photoemission study of thethree-dimensional perovskite-type SrVO$_3$. Observed spectral weightdistribution of the coherent part in the momentum space shows cylindrical Fermisurfaces consisting of the V 3$d$ $t_{2g}$ orbitals as predicted bylocal-density-approximation (LDA) band-structure calculation. The observedenergy dispersion shows a moderately enhanced effective mass compared to theLDA results, corresponding to the effective mass enhancement seen in thethermodynamic properties. Contributions from the bulk and surface electronicstructures to the observed spectra are discussed based on model calculations.Comment: 5 pages, 5 figure
