Electrons on liquid helium in a resonator

A two-dimensional (2D) sl~cct of clectrons 011 thin helium films forms an interesting herd for studying low-dimensional systems. A11 these phenomena are developed under

Shown are the helium film thicknesses, d, measured at two different positions of the sample, one on the upper and one on the lower segment at 1.7 K.. The typical experimental

In the measurements of figure 3, the gate was opened completely for a long time (> 1 s) in order to collect all the mobile electrons present in the source on the pick-up

The film thickness was about 20 nm……… 67 6.1 The variation of the pick-up current as the helium level drops (this procedure called pump-run) is shown. This process corresponds

In that work, 6 the contributions of electron–electron interac- tion and vapour-atom motion were separated, but direct evidence that the interaction of the electrons with the

V (x) is the voltage wh ic h corresponds to the depth ofthe potential we il in which the electrons are stored. the electrostatic energy of the electrons due to Coulomb

δ(x) is the corrugation profile (a + b) is the corrugated structure period, and ζ (x) is the profil of the helium film R is the radius of curvature of the capillary condensed

In summary, we have measured the transport properties of a strongly correlated electron system on the surface of liquid helium at a point constriction formed by a split-gate
