  • Unidirectional Charge Transport via Ripplonic Polarons in a Three-Terminal Microchannel Device

    A. O. Badrutdinov , D. G. Rees , J. Y. Lin , A. V. Smorodin , D. Konstantinov

    … We study the transport of surface electrons on superfluid helium through a microchannel structure in which the charge flow splits into two branches, one flowing straight and one turned at 90°. … However, when the electrons are dressed by surface excitations (ripplons) to form polaronlike particles with sufficiently large effective mass, all the charge follows the straight path due to momentum conservation. …
