The ratio of the electric transverse current to the longitudinal spin current as a function of the Fermi energy counted from the bottom of the conduction band, with inset the geometry of the cross-shaped structure in our calculation. The calculation was carried out on a square lattice with the total width , the effective electron mass , and the Rashba spin-orbit coupling strength .
