Abstract

The strongly correlated electron material, vanadium dioxide (VO

_{2}

), has seen considerable attention and research application in metal-oxide electronics due to its metal-to-insulator transition close to room temperature. Vacuum annealing a V

_{2}

O

_{5}

(010) single crystal results in Wadsley phases (V

_{n}

O

_{2 n + 1}

, n > 1) and VO

_{2}

. The resistance changes by a factor of 20 at 342 K, corresponding to the metal-to-insulator phase transition of VO

_{2}

. Macroscopic voltage-current measurements with a probe separation on the millimetre scale result in Joule heating-induced resistive switching at extremely low voltages of under a volt. This can reduce the hysteresis and facilitate low temperature operation of VO

_{2}

devices, of potential benefit for switching speed and device stability. This is correlated to the low resistance of the system at temperatures below the transition. High-resolution transmission electron microscopy measurements reveal a complex structural relationship between V

O

, VO

_{2}

and V

O

crystallites. Percolation paths incorporating both VO

_{2}

and metallic V

O

_{13}

are revealed, which can reduce the resistance below the transition and result in exceptionally low voltage resistive switching.
