Abstract
High frequency Nanoelectromechanical resonator is one of the most significant countermeasures for high sensitivity mass sensing. A membrane resonator provides stable property and therefore is widely used for the purpose. Of all the membrane materials, Graphene, a new material that won the Nobel Prize in 2010, can be considered as a semiconductor and patterned into arbitrary shapes. Due to its easiness of controlling, graphene has called more and more attention in recent years. This paper analyzed the fundamental mechanisms of both single-layer and multiple-layer graphene resonators with diverse membrane shapes. Based on the analyses, a theory that could be applied to designing the high sensitivity mass sensor is proposed. Moreover, two key issues of mass sensors, i.e., the responsivity and sensitivity, are also computed. The study is directed to outline a theoretical framework for graphene resonators and its application in mass sensing.
