Slip electron flow in GaAs microscale constrictions
Daniil I. Sarypov, Dmitriy A. Pokhabov, Arthur G. Pogosov +4
Hydrodynamic electron transport in solids, governed by momentum-conserving electron-electron collisions, offers a unique framework to explore collective phenomena. Within this fram…
The role of small-angle electron-electron scattering in transverse magnetic focusing experiment
Dmitry A. Egorov, Dmitriy A. Pokhabov, Evgeny Yu. Zhdanov +4
We demonstrate the crucial role of small-angle scattering in transverse magnetic focusing (TMF) in ballistic GaAs/AlGaAs heterostructures. Measurements in various samples show that…
Electronic state back action on mechanical motion in a quantum point contact coupled to a nanomechanical resonator
Andrey A. Shevyrin, Askhat K. Bakarov, Alexander A. Shklyaev +1
In a nanomechanical resonator coupled to a quantum point contact, the back action of the electronic state on mechanical motion is studied. The quantum point contact conductance cha…
Temperature Dependence of Electron Viscosity in Superballistic GaAs Point Contacts
Daniil I. Sarypov, Dmitriy A. Pokhabov, Arthur G. Pogosov +4
Electron transport in suspended and non-suspended GaAs point contacts (PCs) of different widths is experimentally studied. The superballistic contribution to the conductance, that…
