Fig. 1From: Analysis of the Negative-SET Behaviors in Cu/ZrO2/Pt DevicesSEM images of the as-fabricated devices. a SEM image of the device with crossbar structure. Device area is 25 μm2 (5 × 5 μm). The ZrO2 layer is patterned to uncover the Pt bottom electrodes. b Cross-sectional SEM image of the Cu/ZrO2/Pt device. The thickness of ZrO2 layer is 10 nmBack to article page
