Magnetic moments of the carbododecahedron (C20 fullerene) with charges from (−5) to (+4) (in units of the elementary charge e) were calculated by linear combination of atomic orbitals method at the density functional level. It is established that the C20 in the charge state (−1) and the multiplicity 2 has the lowest total energy, while for charge s...

By using Poincaré–Bogolyubov method the nonlinear equations which describe an electromechanical vibrator based on the graphene nanoribbon are studied. A vibrator is proposed scaled to the molecular level based on the funnel-like tin phthalocyanine macromolecule. We present parameters for this device acting as a generator of electric vibrations.

The motion of a conduction electron in a quasi-one-dimensional wire placed into a dielectric environment with distributed inductance is considered. The possibility of the existence in the wire of an inductive soliton (or inducton) is shown and its parameters are estimated. The inducton current waveform is compressed with an increase of inductance.

Quantum-chemical semi-empirical molecular-orbital calculations of zigzag graphene nanoribbons (nzGNRs) were done for the number of zigzag carbon chains n = 4 and 10. The antiferromagnetic (AFM) nature of zGNRs' ground state was confirmed. The energy difference between AFM and ferromagnetic (FM) states was calculated, and dimerization patterns of th...

The changes of dynamical behaviour of a single fullerene molecule inside an armchair carbon nanotube caused by the structural Peierls transition in the nanotube are considered. The structures of the smallest C20 and Fe@C20 fullerenes are computed using the spin-polarized density functional theory. Significant changes of the barriers for motion alon...

Calculated operating parameters for a novel design of a reed switch (based on cantilevered nanotubes filled with magnetic endofullerenes) show the feasibility of room-temperature operation at 100 mV applied voltage.

The influence of bond length dimerization due to Peierls distortions on totally symmetric vibrations of armchair carbon nanotubes is considered theoretically. It is shown that the radial and tangential motions for quinoid type dimerization are mixed and the radial breathing mode for Kekule type dimerization is splitted.

Multiscale simulations of nanotube-based nanoelectromechanical systems (NEMS) controlled by a nonuniform electric field are performed by an example of a gigahertz oscillator. Using molecular dynamics simulations, we obtain the friction coefficients and characteristics of the thermal noise associated with the relative motion of the nanotube walls. T...

Structural and energy characteristics of the smallest magnetic endofullerene Fe@C20 have been calculated using the density functional theory approach. The ground state of Fe@C20 is found to be a septet state, and the magnetic moment of Fe@C20 is estimated to be 8 Bohr magnetons. Characteristics of an (8,8) carbon nanotube with a single Fe@C20 insid...

The structure and properties of C20@(8,8)CNT system are explored by quantum chemical and molecular mechanic calculations.

The changes of dynamical behavior of the system C20@(8,8)CNT at the transition are discussed.

Semiempirical molecular orbital calculations of the (5,5) armchair carbon nanotube give the Kekule structure in its ground state with two essentially different bonds (the bond lengths difference is 0.003 nm). This is a result of the Peierls distortions leading to tripled (compared with undistorted case) translational period. When the armchair nanot...

A new method is proposed for controlling the motion of nanoelectromechanical systems based on carbon nanotubes. In this method, a single-walled nanotube acquires an electric dipole moment owing to the chemical adsorption of atoms or molecules at open ends of the nanotube. The electric dipole moments of carbon nanotubes with chemically modified ends...

The rate of electron-phonon energy transfer at low temperatures has been calculated within the framework of the tight-binding model for the electron spectrum of single-wall "armchair" carbon nanotubes. This rate is proportional to T^2(T - T0), where T and T0 are the electron and phonon temperatures.

We have carried out semiempirical molecular orbital calculations of C^Z+_60 cations and their elongated isomers - C^20+_40 barrelenes. The highest possible metastable charge state of a fullerene ion was found to be C^14+_60. For this charge state the lowest energy isomer is not a spherical buckyball, but an elongated barrelene. For Z ≥ 8, the fissi...
