| Abstract [eng] |
The goal of this dissertation was to extend the possibilities of a total internal reflection ellipsometry (TIRE) method using different plasmonic excitations, such as Tamm plasmon polariton (TPP) and hybrid Tamm-surface plasmon polariton (TPP-SPP). Also, the TIRE method was used at the boundary of the dielectric / dielectric to exploit the biological compatibility of the dielectric coatings with the protein molecules in cases where the surfaces of the metal layers cannot be used. It has been shown that the sensitivity of the multilayred zinc and aluminum oxide structure to the elliptometric parameter Δ is higher than for single layers of zinc or aluminum oxides. The main goal of the studies was related to the generation of hybrid TPP-SPP mode in the TIRE configuration and the application of these modes in plasmonic sensors with substances that change the conductivity of the metal layer. The use of TIRE allows not only to evaluate the percentage composition of the amalgam layer in real time, but also to obtain additional information on the amalgam formation process during the interaction of gold and mercury atoms on the surface. TIRE studies have shown that the penetration of mercury at the gold layer and the formation of amalgam has an exponentially varying gradient refractive index profile. |
