Phonon spectrum and vibrational characteristics of linear nanostructures in solid matrices
The atomic dynamics of linear chains embedded in a crystalline matrix or adsorbed on its surface is studied.
 A linear chain formed by substitutional impurities in a surface layer and at the same time offsetting from this
 layer was analyzed particularly. This system models the activ...

| description | The atomic dynamics of linear chains embedded in a crystalline matrix or adsorbed on its surface is studied.
A linear chain formed by substitutional impurities in a surface layer and at the same time offsetting from this
layer was analyzed particularly. This system models the actively studied experimentally structures in which gas
molecules are adsorbed on the walls of the bundles of carbon nanotubes located in certain medium. It is shown
that the quasi-one-dimensional features are typical for the chains in which the interatomic interaction is higher
than the interaction between the atoms of the chain and the atoms of the crystal matrix. On the local phonon density
of atoms of the chain the transition to quasi-one-dimensional behavior has the form of the kink. In other
words, it is the first (lowest-frequency) van Hove singularity, which in 3D structures (the system under consideration
is generally three-dimensional) corresponds to the transition from closed to open constant-frequency (quasi-plane)
surfaces. The local phonon densities of atoms in the chain have one-dimensional character at frequencies
higher than the frequency of the van Hove singularity. The rms amplitude of embedded chains atoms
vibrations is calculated and the behavior of the atomic vibrations contribution in the low-temperature heat capacity
of the system is analyzed.
