    Electrical Switching in Thin Film Structures Based on Transition Metal Oxides by A. Pergament, G. Stefanovich, V. Malinenko, A. Velichko

    Published 2015-01-01
    “…Electrical switching, manifesting itself in the nonlinear current-voltage characteristics with S- and N-type NDR (negative differential resistance), is inherent in a variety of materials, in particular, transition metal oxides. Although this phenomenon has been known for a long time, recent suggestions to use oxide-based switching elements as neuristor synapses and relaxation-oscillation circuit components have resumed the interest in this area. …”
