About some thermodynamical properties of cylindrical nanorods

Abstract

The thermodynamic phonon properties of cylindrical nanorods are analyzed using the Green's function method. This method is suitable for analyses of spatially deformed structures and gives possibility for the calculation of mean values of operator products. Two types of Green functions will be found for axial phonons and for disc phonons. As a consequence of the applied new method the thermodynamic characteristics of cylindrical nanorods: internal energy and specific heat were obtained.
