摘要

The Green's function method, suitable for analysis of spatially deformed structures, is developed in this paper. Configuration dependency and density of the diffusion coefficient have been analyzed, and the result has shown that the maximum density, as well as diffusion coefficient, is in the center of the quantum dot. It has also been found that specific heat, as well as thermal conductivity, is exponentially small at low temperatures. It has been concluded that they possess high superconductive, thermal and acoustic insulation properties in thin films. The spatial dependence of physical properties of thin films has been shown by introducing boundary conditions for the outermost (marginal) layers of films: n_z = -1 and n_z = N_z + 1.
