Description

We propose a homogeneous nanoscaled (250 nm) bilayered Pr0.7Ca0.3MnO3 (PCMO)-based memory device that exhibits low power and good memristive switching behavior. Accurate control of the oxygen-deficient (PCMO3-x) layer thickness promotes oxygen migration between PCMO3-x and stoichiometric PCMO (PCMO3). The bilayered PCMO structure was confirmed by X-ray photoelectron spectroscopy analysis. (copyright 2011 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)
