  Graphene/carbon-nanotube (CNT) hybrid material can be useful in energy
storage and nanoelectronic technologies. Here we address the CNT-oscillator
encapsulated in a graphene-nanoribbon (GNR) trench as a novel design, and
investigate its properties via classical molecular dynamics simulations. Since
the energy barrier was very low while the CNT was encapsulated in the GNR
trench, the CNT absorbed on the GNR surface could easily be encapsulated in the
GNR trench. MD simulations showed that the CNT oscillator encapsulated in a GNR
trench is compatible with simple CNT oscillators, so we anticipate that the CNT
in GNR trench could work as an oscillator. So we can anticipate that the CNT
encapsulated in a GNR trench can be applied to ultra-sensitive
nanoelectromechanical oscillators, and this system has the possibility to be
applied to relay-switching devices, and to shuttle memory.
