Abstract The Wigner solid (WS) on a liquid4He surface is accompanied with the periodic surface deformation, i.e. the ripplons whose wavevectors equal the reciprocal WS lattice vectors. This unique situation plays a crucial role in the dynamics of the WS. We have performed an extensive measurement of the ac Corbino conductivity σxx. The WS conductivity shows extremely nonlinear behavior, and it jumps abruptly at a certain input voltage. The threshold input voltage Vth varies as VthαB−0.8f−1ns 1.5E⊥, where B, f, ns, and E⊥ are magnetic field, frequency, electron density and pressing electric field, respectively. We have interpreted the σxx jump as the collective sliding of the electrons out of the surface deformation.
