Abstract
Nanomechanical resonators enable a range of precision measurements in air or vacuum, but strong viscous damping makes applications in liquid challenging. Recent experiments have shown that fluid damping is greatly reduced in fluidic embedded-channel microcantilevers. Here we report the discovery of nonmonotonic energy dissipation due to the fluid in such devices, which leads to the intriguing prospect of enhancing the quality factor upon miniaturization. These observations elucidate the physical mechanisms of energy dissipation in embedded-channel resonators and thus provide the basis for numerous applications in nanoscience and biology.
