Investigation of Solid State Reaction in Silver/Tin Nanostructured Thin Films
Nora Samy Sdky Mohareb;
Abstract
The present thesis is devoted to investigate the solid-state reaction in the nanoscrystalline Ag/Sn thin film system at room temperature (at about 298K). The investigation includes:
1. The different individual film thicknesses of Ag/Sn system were prepared by Direct Current (DC) magnetron sputtering instrument.
2. The sputtering rates were calculated from the layer thickness measured by profilometer technique.
3. The structure identification of the samples was investigated by X-ray diffraction (XRD) patterns.
4. The elemental composition of the studied samples was measured by Secondary Neutral Mass Spectrometry (SNMS).
5. The Analysis of the SNMS profiles including:
• Studying the kinetics of the mechanisms based on the grain boundary diffusion process.
• The velocity of the interface by Diffusion-induced grain boundary motion (DIGM) mechanism was calculated.
• The growth rate of the Ag3Sn intermetallic phase by Diffusion-induced recrystallization (DIR) mechanism was estimated.
Keywords: GB diffusion; Thin film reactions; Nanostructure.
