“…Phonon participation in thermodynamic properties (or heat capacitance temperature behavior, i.e. generallyin heat transferring) in thin film was found in our previous paper (Lazarev et al, 2000;Jaćimovski et al, 2004;Šetrajčić et al, 2007;Ilić et al, 2007;Šetrajčić et al, 2009). Getting that, when k → 0 (in long-wave approximation: 4 sin 2 (ak x /2) + sin 2 ak y /2 ≈ a 2 k 2 , k 2 = k 2 x + k 2 y ), energies of all three phonon branches have non-zero values, it can be utilized dispersion relations 22, 49 and 64, in somewhat simplified form:…”

“…Depending on what material is used as a coating, thermal conductivity can be altered. 15 Unlike in the previous papers, 16 here we will try to observe the difference between the characteristics of different nano-crystalline structures: ultrathin films, composite films, i.e. superlattices, nanorods and quantum dots, we were interested in whether the quantum size effects (quantum confinement), quantum (de)coherence and influence of boundary conditions, strengthen or weaken in nanosamples.…”
