Mapping metal/insulator nanodomains switching in V 2 O 3 by variable-temperature electron spectromicroscopy investigations
Résumé
Taming abrupt phase transitions existing in transition metal oxides is considered as a promizing approach for the development of advanced information processing and storage systems. V2O3 is a prototypical system exhibiting metal-to-insulator transitions (MITs) that can be activated under controlled external stimuli such as temperature (T), pressure, or chemical doping [1,2,3]. A precise and detailed understanding of these electronic transitions in Mott insulators and strongly correlated systems such as (V1-xCrx)2O3 is essential to further enhance their potential capabilities for non-volatile memories [4] and neuromorphic applications [5].
