摘要
将碳纤维表面改性后,依据其尺寸效应和表面特性,设计了一种十字交叉碳纤维忆阻器模型。分析了模型的阻变机理,定性地从理论上指出,由束缚电荷产生的电场对忆阻效应起了决定作用。对该模型结构、导电机理和材料属性进行分析讨论,推导出了忆阻器的解析公式。对其各个参数的影响进行了分析与比较,仿真结果发现该模型电压电流特性曲线(voltage-current characteristic curve,V-I)能够与惠普模型相吻合,呈现典型的忆阻特征。实验测量结果与仿真结果基本一致。
Based on the size effect and surface characteristics of surface modified carbon fiber,a cross carbon fiber memristor model was designed.The resistance switching mechanism of the model was analyzed,and in theory,it was qualitatively pointed out that the electric field induced by the bound charge play an important role on memristive effect.The structure,conduction mechanism and material properties of the model were discussed,and an analytical voltage-current equation was derived.The parameters influencing the characteristics of the memristor were analyzed and compared.The simulation results find that the voltage-current characteristic curves(V-I)can coincide with the HP model,and present a typical memristor characteristic.The experimental result is coincident with that of simulation.
