论文摘要
在现场发射实验期间通过电流特征表现出的磁滞通常被认为是在实际应用方面不受欢迎的。但是，这是针对回忆设备的吸引力的。我们开发了一个两阶段模型来描述滞后特性，特别关注该系统，该系统包括由底物上的单层石墨烯片制成的阴极。除滞后外，电流电压曲线还显示出一种不寻常的自我交叉行为。提出的回忆模型可用于定量描述不同的滞后特征，例如突然的变化和自我交叉以及理解（以及建模）与平面石墨烯发射器相关的过程。
Hysteresis exhibited by current-voltage characteristics during field-emission experiments is often considered undesirable in terms of practical applications. However, this is an appealing effect for the purposes of memristive devices. We developed a two-stage model to describe hysteretic characteristics, with a particular focus on the system which includes a cathode made of a single-layered graphene sheet on a substrate. In addition to hysteresis, the current-voltage curves display also an unusual self-crossing behavior. The presented memristive model can be used for quantitative descriptions of different hysteretic characteristics such as abrupt changes and self-crossings and for understanding (and modeling) the processes associated with field emission from plane graphene emitters.
