Human made mechanical resonators have been around for a thousand years. Early applications included musical instruments and chronographs operating in millihertz to kilohertz frequencies while more recent interest has turned ultra-high frequency resonators and oscillators suitable for wireless technologies, mass sensing and even biological applications. The trend has been towards small, stiff and low mass from micro-electro-mechanical systems towards nano-electro-mechanical systems. Nanomechanical resonators are used in myriad of applications including mass sensing, charge detection, biosensing and RF communications. New nano-materials such as carbon nanotubes, graphene, zinc oxide nanobelts, and silver-gallium nanowires are good candidates for high frequency mechanical nanoresonators due to their excellent physical properties and therefore is the subject of this study using COMSOL Multiphysics® models.
