Application of Surface Waves for Studying the Characteristics of Gas-Trapping Sensors Located on a Solid Surface

Section: Solid matter
Original Author's Text: English

Abstract: 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.

Key words: volume and surface waves, dispersion relations, amplitude decreasing parameter, adsorbed surface monolayer.
