Anomalous temperature dependence of microwave resonance-induced resistivity of surface-state electrons on liquid image

The behavior of the linear magneto-resistivity View the MathML source of the surface-state electrons (SSE) on liquid View the MathML source exposed to the resonant microwave radiation is experimentally studied in the temperature range corresponding to the crossover between the gas-atom and the ripplon scattering regimes. The variation of View the MathML source near the microwave resonance is attributed to the heating of SSE induced by the absorption of microwaves. At high temperatures, where gas-atom scattering dominates over ripplon scattering, View the MathML source decreases. At low temperatures, where scattering is due to ripplons, View the MathML source is found to increase. The complicated line shape of the resistivity signal observed at the intermediate temperatures is attributed to the interplay between two regimes.
