Abstract:
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 jump indicates that the decoupling occurs from the dynamically deepened surface deformation as a result of the Bragg-Cherenkov scattering of surface waves. Our results also account for the unusual nonlinear transport reported by Glasson et al. [Phys. Rev. Lett. 87, 176802 (2001)10.1103/PhysRevLett.87.176802] considering the electrode geometry.
