| Summary: | Заглавие с экрана We present the results of ab initio study of hydrogen migration paths in Zr layers of a layered Zr/Nb structure using the electron density functional theory. It was found that the height of the diffusion barriers near the interface decrease for the considered diffusion jumps. The length of the diffusion jumps varies ambiguously depending on the shifts of zirconium atoms from the ideal lattice sites as a result of its distortion near the interface |
