Abstract

We study the change in the electronic structure of CeTiO3+δ across the δ-controlled metal-insulator (M-I) transition. X-ray-absorption spectroscopy shows the formation of hole states with substantial O 2p character as a function of δ. Ultraviolet photoemission spectroscopy confirms the gap (
