Dear all:
I wonder how the adhesion between Al and Au is. I am going to deposit Au on top of Al layer.
Regards.

Adhesion is the force that holds two materials together when they are in contact. In materials science, it is important because it determines the strength and durability of materials and is crucial for designing and developing new materials for various applications.
In this study, the adhesion of Al and Au is investigated using atomic force microscopy (AFM) and scanning electron microscopy (SEM). The surfaces of Al and Au are brought into contact and the force required to separate them is measured, providing information about the strength of their bond.
The adhesion between Al and Au is affected by several factors such as surface roughness, interfacial chemistry, and temperature. Surface roughness can increase the contact area between the materials, leading to a stronger bond. Interfacial chemistry, including the presence of oxides, can also influence the adhesion. Temperature can affect the diffusion of atoms at the interface, altering the strength of the bond.
Understanding the adhesion between Al and Au can have various applications in materials science and engineering. It can help in the development of stronger and more durable materials for use in electronic devices, aerospace, and biomedical applications. It can also aid in the design of better adhesives for joining different materials together.
Future research in investigating the adhesion of Al and Au could focus on studying the effect of different surface treatments on the bond strength, such as using surface modifiers or coatings. Additionally, researchers could investigate the adhesion between Al and Au at different temperatures and under various environmental conditions to better understand the mechanisms behind the bond formation and its stability over time.
