Narrowband Nanomechanical Mass Spectrometry using Nonlinear Response of a Graphene Membrane
Artikel i vetenskaplig tidskrift, 2010

We propose a scheme to measure the mass of a single particle using the nonlinear response of a 2D nanoresonator with degenerate eigenmodes. Using numerical and analytical calculations, we show that by driving a square graphene nanoresonator into the nonlinear regime, simultaneous determination of the mass and position of an added particle is possible. Moreover, this scheme only requires measurements in a narrow frequency band near the fundamental resonance.
