As high-quality single-crystal materials used in electronic devices approach the microscale
and nanoscale, charge-transport phenomena in these devices result in inhomogeneous …

Vortices are the hallmarks of hydrodynamic flow. Strongly interacting electrons in ultrapure
conductors can display signatures of hydrodynamic behaviour, including negative non-local …

The charge carriers in a material can, under special circumstances, behave as a viscous
fluid. In this work, we investigated such behavior by using scanning tunneling potentiometry …

We study hydrodynamic and ballistic transport regimes through nonlocal resistance
measurements and high-resolution kinetic simulations in a mesoscopic structure on a high …

Viscous fluid in an ultrahigh-mobility two-dimensional electron gas (2DEG) in GaAs/AlGaAs
quantum wells is systematically studied through measurements of negative …

The electronic analog of the Poiseuille flow is the transport in a narrow channel with
disordered edges that scatter electrons in a diffuse way. In the hydrodynamic regime, the …

Direct current in clean semiconductors and metals was recently shown to obey the laws of
hydrodynamics in a broad range of temperatures and sample dimensions. However, the …

The hydrodynamic regime of electron transport has been recently realized in conductors
with ultralow densities of defects. Although relaxation processes in two-dimensional (2D) …

In high-mobility materials, conduction electrons can form a viscous fluid at low temperatures.
We demonstrate that in a high-frequency flow of a two-dimensional electron fluid in a …

The diffusion of photogenerated holes is studied in a high-mobility mesoscopic GaAs
channel where electrons exhibit hydrodynamic properties. It is shown that the injection of …
