Direct observation of the mass renormalization in SrVO3 by angle resolved photoemission spectroscopy
Abstract
We have performed an angle-resolved photoemission study of the three-dimensional perovskite-type SrVO3. Observed spectral weight distribution of the coherent part in the momentum space shows cylindrical Fermi surfaces consisting of the V 3d t2g orbitals as predicted by local-density-approximation (LDA) band-structure calculation. The observed energy dispersion shows a moderately enhanced effective mass compared to the LDA results, corresponding to the effective mass enhancement seen in the thermodynamic properties. Contributions from the bulk and surface electronic structures to the observed spectra are discussed based on model calculations.
