Significant new experiments are planned to further elucidate the                nature of the hexatic phase that the investigator identifies in                 the melting of the two-dimensional electron layer.  Theories of                 the electron-ripplon interaction will be tested, the polaron                    state will be looked for in this system, and Bragg scattering of                laser light from the electron dimples will be studied.  Although                in the crystal phase the electron velocity is large enough that                 the dimples don't form, the possibility exists that the dimples                 can form in the hexatic phase where the density of dislocations                 is small.  Further study of the correlations in the classical                   electron fluid will be made.  A search will be made for two-                    dimensional superconductivity in this layer since a small wake in               the helium surface as an electron moves in an electric field                    provides an attractive potential for electron-electron pairing                  via this electron-ripplon coupling mode.
