a Quantum well. b Resonant level. c Band convergence. d Band curvature and e band anisotropy. In d and e, the position EF is assumed to be the same for the light band, heavy band, and anisotropic band, indicating the same S. The difference in the μ of light- and heavy-bands and along different directions of the anisotropic band is indicated.
