(a) XRD spectra of the thermally oxidized films prepared on (i) and (ii) substrates, which show the three peaks of the rutile phase, and (b) bipolar resistive switching of the film measured at room temperature. Current flows from Ag to Pt electrode in positive bias and vice versa in negative bias though absolute values are shown in both cases for logarithmic scale.
(a) Transient characteristics of the HRS and LRS measured at room temperature and (b) switching operation in the pulse mode. A series resistance of was used in the case of pulse set operation to control the resistance of the LRS.
(a) characteristics with current compliances of and measured at and (b) dependence of on-state resistance on set compliance current obtained at .
(a) On-state resistance measured with different temperatures and (b) dependence of set voltage on temperature.
