氧化物忆阻器的分子动力学模拟:热效应

Molecular dynamics simulations of oxide memristors: thermal effects

S. E. Savel'ev, A. S. Alexandrov, A. M. Bratkovsky, R. Stanley Williams

摘要:

我们已经扩展了我们最近的忆阻器的分子动力学模拟,包括在设备的操作过程中出现的移动离子物种的热不均匀性的影响。模拟结果表明,一个有吸引力的短程氧空位之间的相互作用和增强的局部温度在创建/破坏导电氧通道之间的竞争。这种竞争将强烈影响忆阻器件的性能。

英文摘要:

We have extended our recent molecular-dynamic simulations of memristors to include the effect of thermal inhomogeneities on mobile ionic species appearing during operation of the device. Simulations show a competition between an attractive short-ranged interaction between oxygen vacancies and an enhanced local temperature in creating/destroying the conducting oxygen channels. Such a competition would strongly affect the performance of the memristive devices.
