Ss. Sokolov et al., RIPPLON-LIMITED MOBILITY OF SURFACE ELECTRONS ON THICK-FILMS OF HE-3 OVER HE-4, Physical review. B, Condensed matter, 55(21), 1997, pp. 14473-14478
The electron mobility due to the scattering by ripplons is calculated
for surface electrons localized over a thick layer enriched with He-3
above the He-3-He-4 mixture. The temperature-dependence of the mobilit
y is determined for several thicknesses of the layer and small holding
electric fields normal to the Liquid helium surface. The mobility of
surface electrons over bulk pure He-3 is also considered, and the resu
lts are in excellent agreement with the available experimental data, i
n spite of the estimates of strong ripplon damping in He-3.
