A memristive phenomenon was observed in macroscopic bulk negative temperature coefficient nickel monoxide (NiO) ceramic material. Current-voltage characteristics of memristors, pinched hysteretic loops were systematically observed in the Ag/NiO/Ag cell. A thermistor-based model for materials with negative temperature coefficient was proposed to explain the mechanism of the experimental phenomena. Most importantly, the results demonstrate the potential for a realization of memristive systems based on macroscopic bulk materials.
在宏观块状负温度系数镍 monoxide(NiO)陶瓷材料中观察到了一种忆阻现象。在 Ag/NiO/Ag 电池中系统地观察到了忆阻器的电流-电压特性,出现了夹断滞后回线。提出了一个基于负温度系数材料的热敏电阻模型,以解释实验现象的机制。最重要的是,这些结果表明基于宏观块状材料实现忆阻系统的潜力。
