Abstract
Solid phase reaction of bi-metallic thin films of zinc-molybdenum was thermally induced in
order to investigate the diffusion kinetics of this bi-metallic system. The Zinc-Molybdenum bilayers
were prepared by depositing a 50 nm thin film of Zinc on a substrate, followed by
deposition of 50 nm layer of Molybdenum onto the Zinc film. All this was done in the electron
beam evaporation chamber in sequential manner without breaking vacuum. The substrate
temperature was at room temperature, the deposition pressure and the power supply current
were approximately 1 ยด 10-6 mbar and 25 mA respectively. The samples were isothermally
annealed using in-situ real-time Rutherford backscattering spectrometry using the incident
energy of 3.045 MeV. In-situ real-time Rutherford backscattering spectrometry enabled the
tracking of atomic diffusion and depth profiling between Zinc and Molybdenum layers while
heating the sample.
