Abstract

The work is devoted to investigations of physical and chemical processes taking place at the boundary between a thin gold film subjected to low-temperature annealing and gas or liquid media. Besides, the work is aimed to research formation of protective, stabilizing and orienting ones in optimization of characteristics inherent to biochemical sensors based on the effect of optical excitation of the surface electromagnetic wave in the thin gold film as well as in investigations of the reflection angular function when using the mode of attenuated internal total reflection. Shown is the necessity to apply the procedure of 120°C temperature annealing that can result in smoothing a small-scale relief of the gold surface and obtaining some optimal parameters of a resonance curve as well as in formation of defectless protective and stabilizing nano-dimensional layers. To protect gold surface, studied are several mechanisms of layer formation in the cases of gold thiolate and gold sulfide. The way of oriented fixation of a sensitive molecular layer using the non-organic cooper aminopentacyanoferrate layer is worked out.
