Improved cycling stability and ON/OFF ratio of SrFeO_x topological phase transition memristors using a La_0.7Sr_0.3MnO₃ bottom electrode

Abstract

Single-crystal BM-SFO films with horizontal superlattice-like stripes were epitaxially grown on LSMO bottom electrodes and Au/SFO/LSMO memristors exhibit excellent I–V cycling stability and improved ON/OFF ratio.
