Memristor properties of high temperature superconductors
摘要：
综述了4类高温超导体的忆阻特性或阻性开关效应的研究进展，旨在揭示高温超导体的功能特性，展望基于高温超导体的忆阻器的应用前景，寻找强关联性的新机制，实现新一代忆阻器。这些属性是：在氧掺杂时经历金属绝缘体转变、传输各向异性、存在电荷库，通过该电荷库进行导电铜氧层的掺杂。这些是允许在忆阻器中使用它们的HTSC的主要功能特性。通过研究基于高温超导体的异质结中的阻变的双极效应的实例，示出了如何可以基于高温超导体利用它们的功能特性来形成忆阻器结构。
英文摘要：
The review of studies on memristive properties or effect of resistive switchings in four classes of high temperature superconductors is presented in order to reveal functional properties of HTSCs which become apparent in the effects under discussion, prospects of usage of high temperature superconductors based memristors in applications and search for new mechanisms of strongly correlated nature to realize new generation memristors. The properties are: undergoing metal insulator transition at oxygen doping, transport anisotropy, existence of charge reservoirs through which doping of conductive copper oxygen layers is carried out. These are the main functional properties of HTSCs which permit to use them in memristors. By the example of study of bipolar effect of resistive switching in high temperature superconductors based heterojunctions it is shown how one can form memristor structures based on high temperature superconductors using their functional properties.
