Colossal above-room-temperature metal-insulator switching of a Wadsley-type tunnel bronze

We show evidence of the manifestation of enormous metal-insulator switching ranging up to almost six orders of magnitude in individual nanowires of β'-Cu(x)V(2)O(5). The magnitude and temperature of the phase transition is in strong contrast to data reported over several decades for other Wadsl...

Summary:We show evidence of the manifestation of enormous metal-insulator switching ranging up to almost six orders of magnitude in individual nanowires of β'-Cu(x)V(2)O(5). The magnitude and temperature of the phase transition is in strong contrast to data reported over several decades for other Wadsley-type mixed valence tunnel bronze structures.
