an electron jet pump the Venturi Effect of a fermi liquid
Journal of Applied Physics, 2011Co-Authors: D Taubert, G J Schinner, H P Tranitz, Werner Wegscheider, C Tomaras, S LudwigAbstract:A three-terminal device based upon a two-dimensional electron system is investigated in the regime of nonequilibrium transport. Excited electrons scatter with the cold Fermi sea and transfer energy and momentum to other electrons. A geometry analogous to a water jet pump is used to create a jet pump for electrons. Because of its phenomenological similarity we name the observed behavior the “electronic Venturi Effect.”

Excited electrons scatter with the cold Fermi sea and transfer energy and momentum to other electrons. A geometry analogous to a water jet pump is used to create a jet pump for electrons. Because of its phenomenological similarity we name the observed behavior "electronic Venturi Effect".

electron avalanche amplifier based on the electronic Venturi Effect
Physical Review B, 2010Co-Authors: D Taubert, G J Schinner, H P Tranitz, Werner Wegscheider, C Tomaras, Stefan Kehrein, Stephan LudwigAbstract:Solid State Physics Laboratory, ETH Zurich, 8093 Zurich, Switzerland(Dated: July 12, 2010)Scattering of otherwise ballistic electrons far from equilibrium is investigated in a cold two-dimensional electron system. The interaction between excited electrons and the degenerate Fermiliquid induces a positive charge in a nanoscale region which would be negatively charged for diffusivetransport at local thermal equilibrium. In a three-terminal device we observe avalanche amplifica-tion of electrical current, resulting in a situation comparable to the Venturi effect in hydrodynamics.Numerical calculations using a random phase approximation are in agreement with our data andsuggest Coulomb interaction as the dominant scattering mechanism.
