Graphene Based NEMS and Electric Field Sensor: From Research to Real-World Applications

Graphene nanoelectromechanical (GNEM) switches have recently gained much attention due to their low leakage current, sharp switching, and high ON/OFF ratio. However, one bottleneck in GNEM switches is the irreversible stiction between graphene and the metal contact. This study walks through the various ways by which we overcame this issue while achieving a low pull-in voltage (< 0.5 V), an increased number of cycles (> 50,000) and sub-thermal switching (≈10mV/dec).
