新型的纳米离子器件--原子开关是利用固体电化学反应来控制两个电极之间金属丝的形成和湮灭的。切换操作可以简单地通过施加偏置电压来实现，以使金属原子沉淀在两个电极之间的纳米间隙中或将它们溶解到电极之一上。原子开关的小尺寸使得即使需要原子运动也能够快速切换。它们还具有几个新颖的特性，因为它们是非易失性的，消耗较少的功率，并且具有简单的结构和低导通电阻。为了证明改进当今电子器件的可能性，已经使用原子开关开发了逻辑门和1 kbit非易失性存储器芯片。它们的特性还使得能够制造新型电子器件，例如可以在单个芯片上实现多种功能的高性能可编程逻辑器件。
Novel nanoionics devices, atomic switches, have been developed using a solid-electrochemical reaction to control the formation and annihilation of the metal filament between two electrodes. The switching operation can be achieved simply by the application of a bias voltage to precipitate metal atoms in a nanogap between the two electrodes or to dissolve them onto one of the electrodes. The small size of atomic switches enables rapid switching even though atomic motion is required. They also have several novel characteristics in that they are nonvolatile, consume less power, and have a simple structure and a low on-resistance. Logic gates and 1 kbit nonvolatile memory chips have been developed using atomic switches in order to demonstrate the possibilities for improving present-day electronic devices. Their characteristics also enable the fabrication of new types of electronic devices, such as high-performance programmable logic devices that may achieve a multitude of functions on a single chip.
