ABSTRACT

The dispersion relation for a two-dimensional gas of electrons bound to a helium film on a metal substrate is derived and shown to be linear ink for smallk. Both the bulk compressibility of the “dipole gas” and the response of the electrons in the substrate contribute to the sound velocity. The collision time for electron scattering from third-sound excitations is calculated in the limit of low temperatures, low electron densities, and thin films and the effective mass of self-trapped electrons is estimated.
