Electrically driven metal-insulator switching in -KxV2O5 nanowires Academic Article

abstract

• Metal-insulator transition (MIT) in -K xV 2O 5 nanowires is studied via tuning temperature, voltage, and current. In the temperature-driven case, a massive drop in resistance over 4 orders of magnitude at 380 K is reported [C. J. Patridge, Nano Lett. 10, 2448 (2010)]. Our observation of electrically driven MIT results from a systematic study in any M xV 2O 5 system (M is the intercalation ion). In the voltage-driven case, the threshold voltage follows an exponential relation with temperature. In the current-driven case, a negative differential resistance region is observed. These results suggest that K xV 2O 5 is an interesting oxide system exhibiting strong electrically driven MIT and will hence be useful in several switching applications. 2012 American Institute of Physics.
