H. Yayama et A. Tomokiyo, ANISOTROPY OF CONDUCTANCE IN QUASI-ONE-DIMENSIONAL ELECTRON-SYSTEM ONLIQUID-HELIUM, Czechoslovak journal of Physics, 46, 1996, pp. 353-354
The anisotropic conductance of quasi-one-dimensional electron system o
n the surface of liquid helium supported by a new type of substrate wa
s measured. The substrate used is a glass plate on which stripes of fl
at surface and linear grooves align in parallel alternatively. It is s
hown that the ratio of the conductances of electrons moving along and
across the channels is larger than 470 which is about 2 orders greater
than that obtained so far.
