“…In the seventies, Presland et al 2,3 focused on hillock formation and voiding by surface diffusion on thin silver films. They observed cavity formation on cooling films (5 Å -1 µm in thickness) on which hillock had spontaneously been formed.…”

Aging under mechanical stress: first experiments and related simulations for a silver-based multilayer mirror

et al. 2004

Improving materials and devices reliability is a major concern to the spatial industry. Results are reported for satellite mirrors-like specimens consisting in oxide-protected metal systems. Optical coatings were deposited by electron beam evaporation.Mechanical stress fields in multi-layered materials play an important role. The stress state can have far-reaching implications both in kinetics and thermodynamics. Therefore an integrated apparatus with four-point bending equipment was designed. The technique allowed us to exert stress into a film or a system of films on a substrate concurrently with thermal treatment.In order to achieve the first tests performed with the help of the apparatus, various preliminary characterizations were required. The article reports the preliminary micro-mechanical testing of the materials (ultra micro-indentation to evaluate the elastic modulus of the samples materials and wafer curvature technique to determine the specimen residual stress) and the first ageing experiment. Experimental evidence of accelerated ageing under stress is successfully reported.

“…The agglomerates are found to increase in size as the temperature is increased. [66][67][68] This study mainly focuses on the effect of thermal annealing on the variation of contact angle in the case of two different thicknesses of Ag thin films. Ag thin films have been annealed in four various temperatures of 100, 200, 300 and 400 C for 1 hour.…”

In this approach, Ag thin films have been prepared using electron beam evaporation technique onto a thin film of tin-doped indium oxide coated ordinary glass substrate. The fabricated thin films were annealed in various temperatures: 100, 200, 300 and 400 C and the effect of annealing on their wetting, structural and morphological properties has been investigated. Scanning electron microscopy (SEM), UV-Visible spectroscopy (UV-Vis), diffuse reflectance spectroscopy (DRS), X-ray diffraction (XRD) and contact angle measurement have been applied for the characterization and study of thin film surfaces. The results of SEM exhibit the aggregation and formation of Ag nanoparticles on the surface of substrate changed through increasing of annealing temperature. The presence of mixed In 2 O 3 -Ag phases in the as-prepared and annealed samples was confirmed by XRD pattern. Optical behavior of thin films was followed by using diffuse reflectance spectroscopy. Wettability studies showed that the contact angle of prepared thin films was influenced by various parameters such as annealing temperature, surface morphology and composition of thin films.
