Title: V{sub 3}O{sub 5}: Insulator-metal transition and electric-field-induced resistive-switching

Abstract

V{sub 3}O{sub 5} is one of the two vanadium oxides that exhibit insulator to metal transitions above room temperature. We report on the DC I–V characteristics of polycrystalline samples and single-crystals of V{sub 3}O{sub 5} over a wide range of currents. For all samples self-heating induced hysteretic nonlinear conductivity followed at higher currents by onset of negative differential resistivity regime, and finally, at highest currents, by switching to the metallic state. Slow switching towards a partially transformed state with a prolonged memory is typical of polycrystalline samples. High currents applied in the metallic state of one of the single crystals affected the oxygen content of the material and even caused appearance and disappearance of a VO{sub 2} inclusion. Simple and reproducible I–V plots were obtained for a single crystal with the currents that barely induced the metallic state.
