The phenomenon appears for the particular orientation of (B) over right arrow parallel to the samples' surface and orthogonal to the direction of the electric field (E) over right arrow and wave vector of the TRW (K) over right arrow. The results are qualitatively explained taking into account the Lorentz force and a pronounced inhomogeneity of the charge transport and of the TRW parameters. |
