Study on the Negative Resistance Switching Properties in Ti/La_(0.7)Ca_(0.3)MnO_3/Pt Sandwiches Devices
Ti/La_(0.7)Ca_(0.3)MnO_3/Pt结构器件中“负”电阻开关特性研究

The La0.7Ca0.3MnO3(LCMO) thin films with resistive switching properties were grown on Pt(111)/Ti/SiO2/Si substrates by pulsed laser deposition(PLD).X-ray diffraction(XRD) results show that the films exhibited nanocrystalline or noncrystalline.Scanning electrical microscope(SEM) and atomic force microscope(AFM) were employed to characterize the morphology of as-grown films whose surfaces are flat,smooth and dense.The results of electrical test indicate that the Ti/LCMO/Pt structures show a bipolar 'negative'...
