Low-Voltage Electromechanical Switching Based on Low-Dimensional Materials
We report a nanoelectromechanical (NEM) switch fabricated entirely through the bottom-up assembly of low-dimensional materials, comprising graphene, self-assembled molecular spacers and Au nanowires. The device works by electrostatically compressing the molecular spacer, thereby modulating the tunneling current through it. By leveraging the atomically smooth interfaces inherent to low-dimensional materials, we demonstrate that this device can operate without shorting for more than 7000 cycles while demonstrating a low actuation voltage.
