Abstract

Using site-specific soft x-ray emission and absoroption spectroscopy in conjunction with site-specific x-ray photoelectron spectroscopy, we measure the magnitude of the insulating band gap of NiO to be approximately 2.0 eV, comparable to that predicted by our density-functional theory calculations, and note that the insulating character of NiO arises from a mixture of charge-transfer and Mott-Hubbard character corresponding to the Zaanen-Sawatsky-Allen model.
