摘要:

双极型可逆纳米开关是一种具有良好应用前景的新型开关器件。我们进行了分子动力学模拟,模拟系统与氧空位通过现实的潜力和外部偏置电压驱动的相互作用。带电移动空位之间的竞争性短程和长程相互作用导致密度波动和短程有序,同时说明了观察到的实验行为的某些方面,例如忆阻器极性反转。

英文摘要:

Reversible bipolar nano-switches that can be set and read electronically in a solid-state two-terminal device are very promising for applications. We have performed molecular-dynamics simulations that mimic systems with oxygen vacancies interacting via realistic potentials and driven by an external bias voltage. The competing short- and long-range interactions among charged mobile vacancies lead to density fluctuations and short-range ordering, while illustrating some aspects of observed experimental behavior, such as memristor polarity inversion.
