Abstract |
|
|
|
Multilayered pure titanium and palladium films were evaporated alternatively on (1 0 0) monocristalline silicon substrates. Annealing, in a furnace vacuum, was carried out at temperatures ranging from 700 up to 950°C, for 30 min. The obtained samples were analyzed by means of Rutherford backscattering spectrometry, X-ray diffraction and scanning electron microscopy techniques. The interdiffusion of the different elements all with the enhanced transformations occurring at Pd/Ti and Ti/Si interfaces has been investigated.
