      abstract     = {We compared the resistive switching performance of barium
                      strontium titanate (BST) thin films with tungsten (W) and
                      platinum (Pt) top electrodes, respectively. The yield,
                      endurance, and reliability were strongly improved for the
                      samples with W top electrode. Whereas the samples with Pt
                      top electrode show a fast drop in the resistance for both
                      high and low resistance states, the devices with W top
                      electrode can be switched for 10(4) times without any
                      obvious degradation. We attribute the improved switching
                      performance to a reversible oxidation and reduction in a WOx
                      layer at the W-BST interface, which was detected by
                      time-of-flight secondary-ion-mass spectroscopy
                      measurements.},
