Negative Magnetoresistance in Viscous Flow of Two-Dimensional Electrons
Negative Magnetoresistance in Viscous Flow of Two-Dimensional Electrons
At low temperatures, in very clean two-dimensional (2D) samples the electron mean free path for collisions with static defects and phonons becomes greater than the sample width. Under this condition, the electron transport occurs by formation of a viscous flow of an electron fluid. We study the viscous flow of …
