Rezumat:

Thermal conductivity of thin lm is analyzed in this paper. It has been shown that at low
temperatures, thermal conductivity of lm 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 the implantation of light molecules in lm boundaries leads to considerably higher
activation temperatures. Our theoretical results proved to be in agreement with some of the latest
experimental data.
