Abstract
We have measured the mobility of surface state electrons (SSE) on liqu id He-3, mu(3), aiming to study the elementary surface excitations of the Fermi liquid. A gradual increase of mu(3) below 300 mK is attribut ed to the scattering of electrons by ripplons. Ripplons do exist in He -3 down to 100 mK. We observe an abrupt decrease of mu(3), due to the transition to the Wigner solid (WS). The dependences of the WS conduct ivity and mobility on temperature and magnetic field differ from the S SE behavior on liquid He-4.
