摘要: We investigate hysteresis effects in a model for nonvolatile memory devices. Two mechanisms are found to produce qualitatively similar those often experimentally observed heterostructures of transition metal oxides. One them is switching effect based on metal-insulator due strong electron correlations at the dielectric/metal interface. The resistance phenomenon could be experimental realization strongly correlated device.
