The influence that Ti and Cr adhesion layers have on the microscopic and macroscopic properties of Au ultra-thin metal films was investigated at room temperature, with the analysis carried out on both bilayer and multilayer systems in order to obtain a more complete view of the interaction. The obtained results led to the formulation of a revised adhesion model for the Ti/Au and Cr/Au bilayer systems, which gives a description of the adhesion layer-overlayer interaction and can be used by the research community as guide-lines for adhesion layer and thin-film stack engineering. The model was also accompanied by the formulation of recommendations about the use of adhesion layers for different nanofabrication applications. The analysis of Ti/Au/Ti and Cr/Au/Cr multilayer systems allowed to obtain experimental evidence of the type of chemical bonding that leads to the increase of adhesion.

A positive impact of the adhesion layers on the stability of the Au nanostructure at high temperatures was observed with TKD, with Ti and Cr preserving the continuity of the Au layer up to a temperature of 500°C without the observation of dewetting.
