The resistive switching effect of the SrTiO3:Nb (0.05wt %, 0.5 wt %, and 1 wt % Nb) single crystals contact with Ag and Pt, respectively, was studied by in situ monitoring the voltage drop (V-s) across the samples. For Ag/SrTiO3:Nb junction, the response time is as short as 5 ns, which is two orders of magnitude short than that of the Pt/SrTiO3:Nb junction. The effect of metal electrodes on the response time has been discussed, which is related to the barrier height of the junction. c 2010 American Institute of Physics. [doi:10.1063/1.3524216]
