“…54 The expressions introduced here give the possibility to reproduce the shape and quantitative characteristics of the potential energy surface of h-BN bilayer and can be useful for multiscale simulations of such phenomena as atomic-scale slip-stick motion of a h-BN flake attached to STM tip on the h-BN surface, diffusion of a h-BN flake on the h-BN surface and formation of stacking dislocations in h-BN bilayer (analogous to multiscale simulations of the phenomena observed for graphene [4][5][6][7][8][9][10][18][19][20][21][22][23][24][25][26] ).…”

“…Nevertheless, a large number of phenomena related to interaction of 2D layers discovered first for bilayer and few-layer graphene can also be expected for hexagonal boron nitride and can be useful for development of new applications. These phenomena include among others observation of Moiré patterns upon relative rotation of graphene layers, [1][2][3] atomic-scale slip-stick motion of a graphene flake attached to STM tip on a graphene surface, [4][5][6] self-retracting motion of the layers at their telescopic extension, 8 diffusion and drift of a graphene flake on a graphene surface via rotation to incommensurate states 9,10 and observation of dislocations in stacking of graphene layers. 7,[18][19][20][21][22][23][24][25][26] The latter takes place when different parts of the system experience different relative shifts between the layers at the atomic scale and the system gets divided into a number of commensurate domains separated by incommensu-rate boundaries.…”

Principal characteristics of interlayer interaction and relative motion of hexagonal boron nitride (h-BN) layers are investigated by the first-principles method taking into account van der Waals interactions. Dependences of the interlayer interaction energy on relative translational displacement of h-BN layers (potential energy surfaces) are calculated for two relative orientations of the layers, namely, for the layers aligned in the same direction and in the opposite directions upon relative rotation of the layers by 180 degrees. It is shown that the potential energy surfaces of bilayer h-BN can be approximated by the first Fourier components determined by symmetry. As a result, a wide set of physical qualintities describing relative motion of h-BN layers aligned in the same direction including barriers to their relative sliding and rotation, shear mode frequency and shear modulus are determined by a single parameter corresponding to the roughness of the potential energy surface, similar to bilayer graphene. The properties of h-BN layers aligned in the opposite directions are described by two such parameters. The possibility of partial and full dislocations in stacking of the layers is predicted for h-BN layers aligned in the same and opposite directions, respectively. The extended two-chain Frenkel-Kontorova model is used to estimate the width and formation energy of these dislocations on the basis of the calculated potential energy surfaces.

“…The ability of free relative sliding and rotation of carbon nanotube walls [4,5] and their excellent "wearproof" characteristics [5] allowed using carbon nanotube walls as movable elements in nanoelectromechanical systems (NEMS). By analogy with the gigahertz oscillator based on carbon nanotubes [6,7], a gigahertz oscillator based on the telescopic oscillation of graphene layers was suggested [3].…”

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 Qfactor values. The perspectives of nanoelectromechanical systems based on relative motion or vibrations of graphene layers are discussed.

Graphene/carbon-nanotube (CNT) hybrid material can be useful in energy storage and nanoelectronic technologies. Here we address the CNT-oscillator encapsulated in a graphenenanoribbon (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.
