Abstract

Based on theoretical modeling, we performed comprehensive investigation on the quantum and thermomechanical noise squeezing effect in nanoresonators made by two platform material systems: silicon and graphene. We discovered that quantum noise squeezing plays an important role in the effort to improve signal-to-noise ratio in graphene-based nanoresonators. The research suggests a viable strategy for implementing graphene-based nanoscale transducers with ultra-high sensitivity that can be potentially utilized to detect a variety of sensing targets, including atomic force, single biological molecule, and gravitational wave.
