Study of the hydrogen diffusion in superlattices by grazing angle neutron reflectometry
This paper deals with the possibility of studying H diffusion in a small depth range (≈80 Å) with grazing angle neutron reflectometry. This new optical and nondestructive technique allowed us to follow the evolution of H in small period superlattices with a small annealing temperature. To illustrate...

Summary: | This paper deals with the possibility of studying H diffusion in a small depth range (≈80 Å) with grazing angle neutron reflectometry. This new optical and nondestructive technique allowed us to follow the evolution of H in small period superlattices with a small annealing temperature. To illustrate this, a superlattice of 10(NiTiH
x
) sputtered on float-glass is studied. Variations in both neutron refractive indices of Ni and TiH
x
layers, the period and the neutron reflectivity of the stratified medium were observed. |
