Surface effects on the Mott-Hubbard transition in archetypal VO
G. Lantz, M. Hajlaoui, E. Papalazarou +9
We present an experimental and theoretical study exploring surface effects on the evolution of the metal-insulator transition in the model Mott-Hubbard compound Cr-doped VO…
Optical properties of V2O3 in its whole phase diagram
I. Lo Vecchio, L. Baldassarre, F. D'Apuzzo +7
Vanadium sesquioxide V2O3 is considered a textbook example of Mott-Hubbard physics. In this paper we present an extended optical study of its whole temperature/doping phase diagram…
Mott-Hubbard transition in V2O3 revisited
P. Hansmann, A. Toschi, G. Sangiovanni +4
The isostructural metal-insulator transition in Cr-doped V2O3 is the textbook example of a Mott-Hubbard transition between a paramagnetic metal and a paramagnetic insulator. We rev…
Atomic and itinerant effects at the transition metal x-ray absorption K-pre-edge exemplified in the case of VO
P. Hansmann, M. W. Haverkort, A. Toschi +5
X-ray absorption spectroscopy is a well established tool for obtaining information about orbital and spin degrees of freedom in transition metal- and rare earth-compounds. For this…
Evolution of the electronic structure of a Mott system across its phase diagram: an X-ray absorption spectroscopy study of (V(1-x)Crx)2O3
F. Rodolakis, J. -P. Rueff, M. Sikora +12
V2O3 is an archetypal system for the study of correlation induced, Mott-Hubbard metal-insulator transitions. Despite decades of extensive investigations, the accurate description o…
Mott transition in Cr-doped V2O3 studied by ultrafast reflectivity: electron correlation effects on the transient response
B. Mansart, D. Boschetto, S. Sauvage +2
The ultrafast response of the prototype Mott-Hubbard system (V1-xCrx)2O3 was systematically studied with fs pump-probe reflectivity, allowing us to clearly identify the effects of…
Inequivalent routes across the Mott transition in V2O3 explored by X-ray absorption
F. Rodolakis, P. Hansmann, J. -P. Rueff +14
The changes in the electronic structure of V2O3 across the metal-insulator transition induced by temperature, doping and pressure are identified using high resolution x-ray absorpt…
Valence band electronic structure of V2O3: identification of V and O bands
E. Papalazarou, Matteo Gatti, M. Marsi +14
We present a comprehensive study of the photon energy dependence of the valence band photoemission yield in the prototype Mott-Hubbard oxide V2O3. The analysis of our experimental…
