Nanowerk  August 15, 2022 In this review article an international team of researchers (Germany, Switzerland) addressed resistive switching devices operating according to the bipolar valence change mechanism (VCM). VCM cells consist of three parts: an electronically active electrode (AE), a mixed ionic-electronic conducting (MIEC) layer consisting of a nanometer-scale metal oxide, and an ohmic counter electrode (OE). They provided detailed insights into the status of understanding of these devices as a fundament for their use in the different fields of application. The review covered the microscopic physics of memristive states and the switching kinetics of VCM devices. Electroforming, a process […]
