标题： Memristive model of hysteretic field emission from carbon nanotube arrays

摘要： 一些电子场发射器的实例表现出其电流-电压特性中的频率依赖性滞回现象。我们认为这样的发射器可以被归类为忆阻系统，并引入一个通用框架来描述它们的响应。作为我们方法的一个具体例子，我们考虑来自碳纳米管阵列的场发射。我们的实验结果表明存在低场滞回现象，这可能是由于在施加电场中一些纳米管的静电对齐所致。我们提出了一个描述这种现象的忆阻模型，其结果与实验结果一致。 显示英文摘要

摘要： Some instances of electron field emitters are characterized by frequency-dependent hysteresis in their current-voltage characteristics. We argue that such emitters can be classified as memristive systems and introduce a general framework to describe their response. As a specific example of our approach, we consider field emission from a carbon nanotube array. Our experimental results demonstrate a low-field hysteresis, which is likely caused by an electrostatic alignment of some of the nanotubes in the applied field. We formulate a memristive model of such phenomenon whose results are in agreement with the experimental results.
