Electronic valence band structure of V2O5 — •Torsten Stemmler, Eric Meyer, and Recardo Manzke — Institut für Physik, Humboldt-Universität zu Berlin, Newtonstr. 15, 12489 Berlin
We present high-resolution ARPES measurements of V2O5 single crystals carried out with synchrotron radiation and He I resonance lamp. The obtained experimentally band structure in k parallel is compared with calculations, e.g.[1] and [2]. The aging behavior of different bands with time is studied. The degradation of the surface due to the high reactivity is discussed referring to the previous reported experimental work, e.g. [3] and [4].
