摘要

我们证明了石墨烯谐振器与氮化硅谐振器的机械模式耦合，从而获得38 dB增益。此外，通过石墨烯热噪声的热机械压缩，我们证明了总体测量灵敏度为3.8 fmHz−1/2。

Thermo-mechanically Squeezed Graphene Amplifier

We demonstrate coupling of mechanical mode of graphene resonator to that of Silicon Nitride resonator, resulting in 38 dB gain. Furthermore, with thermomechanical squeezing of graphene thermal noise, we demonstrate an overall measurement sensitivity of 3.8 fmHz−1/2.
