Electron lone pair distortion facilitated metal-insulator transition in -Pb0.33V2O5 nanowires Academic Article

abstract

• The electronic structure of -Pb0.33V2O 5 nanowires has been studied with x-ray photoelectron spectroscopy techniques. The recent synthesis of defect-free -Pb0.33V 2O5 nanowires resulted in the discovery of an abrupt voltage-induced metal insulator transition. First principle calculations predicted an additional V-O-Pb hybridized "in-gap" state unique to this vanadium bronze playing a significant role in facilitating the transition. We confirm the existence, energetic position, and orbital character of the "in-gap" state. Moreover, we reveal that this state is a hybridized Pb 6s-O 2p antibonding lone pair state resulting from the asymmetric coordination of the Pb2+ ions. 2014 AIP Publishing LLC.
