The nanomechanical resonator composed of two-dimensional
materials
has seen extensive investigations, but the interaction between two
adjacent resonators has not called much attention. The paper reports
a vibration transfer phenomenon within a graphene film covering two
neighboring holes. When an electrostatic excitation was applied to
one of the resonators, vibration signals were detected in both resonators
but with a 90° phase difference, as measured by a microscopic
laser vibrometer. The findings were validated through finite element
simulations and molecular dynamics simulations. It is concluded that
the occurrence of this vibration transfer phenomenon is attributed
to the slip displacement of graphene film within the middle connection
region. The vibration transfer phenomenon sheds light on issues such
as resonator excitation, signal transfer, and modal coupling. Moreover,
two orthogonal signals with a 90° phase difference hold significant
value for applications across various fields, including digital communication
systems.
