Electronic structure of Ca${}_{1-x}$Sr${}_x$VO${}_3$: a tale of two energy-scales

K. Maiti, D. D. Sarma, M. J. Rozenberg +5

We investigate the electronic structure of Ca${}_{1-x}$Sr${}_x$VO${}_3$ using photoemission spectroscopy. Core level spectra establish an electronic phase separation at the surface, lead…
