Application of surface waves for studying the characteristics of gas-trapping sensors located on a solid surface
Artikel i vetenskaplig tidskrift, 2014

Dispersion relations for surface waves and attenuation parameters in a crystal with the impurity monolayer adsorbed on its top are studied. We consider a face-centered cubic crystal with central interaction between the nearest neighbors as a model and calculate the value of m0* for the adsorbed surface monolayer. Beginning from it (m0< m0*), the surface wave splits off the upper edge of the volume spectrum and attenuates non-monotonously (with oscillations), when penetrating into the crystal bulk.
