KxNa1-xNbO3 (0 0.5) was obtained from 8 M total hydroxide concentration after 6 h of reaction at 200 °C. Rietveld refinement of the XRD data revealed that all samples exhibited the secondary NaNbO3 phase. However, the lowest amount (3.74 vol%) was o

We fabricate NbO 2 thin films and measure their transport properties in simple devices. These could be potential components of future memristor devices because of peculiar conductivity variations observed as a function of device current. We find that
