Schematic diagram of semiconductor QW, the constant energy surfaces and the spin orientations of 2DEG. (a) Schematic diagram of semiconductor QW which oriented along the crystallographic direction θ with respect to [100] axis in the crystallographic planes (001), (110), and (111). n is the unit vector along the normal direction of the crystallographic plane. (b) The constant energy surfaces and the spin orientations of 2DEG in (001), (110), and (111) planes.
