The influence of the surface parameter changes onto the phonon states in ultrathin crystalline films
(Elsevier Science Bv, Amsterdam, 2018)
In this paper, we have analytically investigated how the changes in boundary surface parameters influence the phonon dispersion law in ultrathin films of the simple cubic crystalline structure. Spectra of possible phonon ...
Diffusion of phonons through (along and across) the ultrathin crystalline films
(Elsevier Science Bv, Amsterdam, 2017)
Instead of usual approach, applying displacement-displacement Green's functions, the momentum-momentum Green's functions will be used to calculate the diffusion tensor. With this type of Green's function we have calculated ...
