Inelastic processes in gold and copper thin films applied on silica
glass
Abstract
Internal friction in gold and copper thin films applied on surface of
high Q-factor silica glass resonators was investigated. An intensive internal
friction peak connected with low adhesion between the coating and the
substructure is observed at temperature 0...100°C in kilohertz frequency range.
The internal friction in the gold thin film may be significantly decreased by
adding in it a second component that form solid solution with gold and improves
the adhesion of the coating to silica glass. Adding of the second component
decreases grain-boundary and dislocation internal friction too. Stabilization
of dissipation property of the two-component coating is reached by annealing.
