Nanoelectromechanical (NEM) relays have been studied for use in low-power logic applications because of their conspicuous features of (i) zero off-state leakage and (ii) abrupt on/off switching behavior in principle. In this study, a lateral NEM relay is analytically modeled. Then, the pull-in/out voltages, which work as turn-on/off voltages for the device, are estimated quantitatively using equations that explain the operational principle of the NEM relay.

Improving the performance of resistive switching memories, while providing high transparency and excellent mechanical stability, has been of great interest because of the emerging need for electronic wearable devices. However, it remains a great challenge to fabricate fully flexible and transparent resistive switching memories because not enough research on flexible and transparent electrodes, for their application in resistive switching memories, has been conducted. Therefore, it has not been possible to obtain a nonvolatile memory with commercial applications.
