Abstract
A current-controlled memristive one-port was constructed from cobalt monoxide (CoO) using a traditional solid reaction method at 1150 °C in argon atmosphere. Hysteretic current–voltage (I–V) characteristics and resistance switching were investigated in the as-obtained Ag/CoO/Ag cell. Dependences of the I–V loop on voltage range (0 to 10, 11, and 12 V), voltage scan rate (0.1, 1, and 10 V/s), and temperature (323, 373, and 423 K) were reported. A thermistor model for materials with negative temperature coefficient (NTC) was proposed for explanation of the mechanism. An ideal NTC thermistor-based memristive one-port would broaden the applications of memristors and memristive devices.
