Abstract

We report the measurement of electrical transport of the two-dimensional Wigner solid (WS) formed on the free surface of superfluid 3He-B down to 230 μK. The resistance R(T) dramatically decreases as temperature T decreases, obeying Arrhenius' law, R(T) ∝ exp[-Δ(T)/kBT], with Δ(T) which we assign to the superfluid energy gap. That is, the scattering of 3He quasiparticles by the WS determines the transport. The resistance depends systematically on the static electric field which presses the WS toward the liquid surface. We propose that the WS acts as a powerful probe for the study of the superfluid 3He.
