研究了自旋轨道相互作用对交叉结结构电子输运性质的影响。结果表明，它导致了左向和右向电子波的自旋极化。因此，适当极化的入射电子波诱导电压降垂直于所考虑的四端交叉结构的源极和漏极之间的直流电流下。对于技术上可用的结构，由此产生的类霍尔电阻估计为10^-3 - 10^-2 h/e^2。在共振附近，这种效应变得更加明显，在那里，类霍尔电阻的符号随着费米能量的变化而改变。
The effect of spin-orbit interaction on electron transport properties of a cross-junction structure is studied. It is shown that it results in spin polarization of left and right outgoing electron waves. Consequently, incoming electron wave of a proper polarization induces voltage drop perpendicularly to the direct current flow between source and drain of the considered four-terminal cross-structure. The resulting Hall-like resistance is estimated to be of the order of 10^-3 - 10^-2 h/e^2 for technologically available structures. The effect becomes more pronounced in the vicinity of resonances where Hall-like resistance changes its sign as function of the Fermi energy.
