Diffusion of Photoexcited Holes in a Viscous Electron Fluid

Diffusion of Photoexcited Holes in a Viscous Electron Fluid

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 holes into such an electron system leads to the formation of a hydrodynamic three-component mixture consisting of electrons a...
