Photoemission evidence for a Mott-Hubbard metal-insulator transition in VO${}_2$

R. Eguchi, M. Taguchi, M. Matsunami +15

The temperature ($T$) dependent metal-insulator transition (MIT) in VO${}_2$ is investigated using bulk sensitive hard x-ray ($\sim$ 8 keV) valence band, core level, and V 2$p-3d$ re…
