Dielectric Permeability of Nanocylinder
(Polish Acad Sciences Inst Physics, Warsaw, 2010)
In the nanocylinder, a cut-off from the molecular crystal, dielectric permeability tensor is investigated. Excitons in the nanocylinder arise due to the exciting of the electron subsystem of the molecule. In evaluation of ...
Phonon Contribution in Thermodynamics of Nano-Crystalline Films and Wires
(Polish Acad Sciences Inst Physics, Warsaw, 2009)
Spectra of possible phonon states, as well as thermodynamic characteristics of nanocrystals (ultrathin film and quantum wire) of simple cubic crystalline structure are analyzed in this paper, using the method of two-time ...
Phonon Contribution in Thermodynamics and Transport Properties of Ultrathin Ceramic Films
(Polish Acad Sciences Inst Physics, Warsaw, 2014)
The dispersion law, density states of phonons, thermodynamics properties and thermal conductivity was analyzed in this paper. It has been shown that at low temperatures, thermal conductivity of thin film is considerably ...
Thermodynamic Characteristics of 1D Structures
(Polish Acad Sciences Inst Physics, Warsaw, 2011)
In this paper 1D crystal lattice is analyzed within harmonic approximation, with one atom per elementary cell and nearest neighbor interaction included. For this type of crystal lattice dispersion relations are well known. ...
Phonon-Induced Thermodynamic Properties of Ultra-narrow Wires
(Polish Acad Sciences Inst Physics, Warsaw, 2018)
In this paper, we investigated the influence of size effect on thermodynamic properties of ultra-narrow wires with a simple cubic lattice, by means of two-time dependent Green functions method, adjusted to confined crystalline ...
