The possibility of designing nanoelectromechanical systems (NEMS) based on
relative motion or vibrations of graphene layers is analyzed. Ab initio and
empirical calculations of the potential relief of interlayer interaction energy
in bilayer graphene are performed. A new potential based on the density
functional theory calculations with the dispersion correction is developed to
reliably reproduce the potential relief of interlayer interaction energy in
bilayer graphene. Telescopic oscillations and small relative vibrations of
graphene layers are investigated using molecular dynamics simulations. It is
shown that these vibrations are characterized with small Q-factor values. The
perspectives of nanoelectromechanical systems based on relative motion or
vibrations of graphene layers are discussed.Comment: 19 pages, 4 figure
