  • Abstract The effective conserved orbital current is composed of the conventional orbital current and the torque orbital current. We use Kubo formula and analytically calculate the intrinsic orbital Hall conductivity in the generic k-linear spin-orbit coupling semiconductor systems. We find that the magnitude of the conventional orbital - Hall conductivity depends on the orientation of the system. Further, when the torque orbital Hall conductivity is considered, the resulting absolute value of the total orbital - Hall conductivity reaches a maximum when the orbital current occurs in the direction with the smallest band splitting.
