The electronic subsystem of ultrathin films was analysed using Green's function method including quantum size effect and the effect of boundaries to Hamiltonian parameters. Diagonal components of Green's functions were evaluated which enabled a complete insight into the thermodynamical...

Thermal conductivity of thin film is analyzed in this paper. It has been shown that at low temperatures, thermal conductivity of film is considerably lower than that of bulk structure. Also, the dependence of activation energy on boundary conditions has been investigated. It has been found that...
