Abstract. Reported in this paper are the results of investigations aimed at scattering of conduction electrons at the tungsten (110) surface covered with hydrogen submonolayers, in which the effect of increasing the specularity of surface scattering of conduction electrons after formation the adsorption phase W(110)-(11)H has been confirmed. The monolayer coverage with hydrogen was formed as a result of the low-temperature adsorption involving extrinsic precursor adsorption molecular states. The experiments were carried out using two techniques based on the classical galvano-magnetic size phenomena – the static skin effect and transverse magnetoresistance. It has allowed to confirm the surface nature of the observed effect.
Keywords: surface scattering of conduction electrons, surface electron states, adsorption, static skin effect, transverse magnetoresistance. | ||
