Wafer-scale suspended graphene for sensing applications

Graphene, the first among an expanding class of two-dimensional (2D) materials, is one of the more promising candidates for future sensing applications due to its high intrinsic carrier mobility, its thickness of 0.334 nm, large specific surface area, and Young's modulus of approximately 1 TPa. These excellent properties allow the current sensor technology to shrink showing faster and more powerful performances accordingly to the market demand.

In the most common sensing technologies, suspended atomically thin graphene structures are the principal functional components. Their suspended movement translates into the sensing principle of pressure sensors, microphones, loudspeakers, photodetectors, NEMS switches, and other devices.

However, achieving scalable wafer-scale suspended graphene membranes still show high difficulties in terms of fabrication yield and CMOS compatibility.
