Nonlinear transport of the Wigner solid on superfluid 4He in a channel geometry.


Nonlinear transport of electron crystal floating on superfluid 4He is investigated in channels 8 and 15 mum in width, where the electron velocity and driving electric field are uniform. At a high excitation, we observe a jump in the velocity caused by the decoupling of the electrons from the underlying surface deformation. The obtained driving field at the… (More)
