a 3D illustration of Parabolic and Kane bands with asymmetric conduction and valence bands. The features of conduction band nestification and relative flat valence band are presented. b E ~ k dispersions of parabolic (solid blue line) and Kane bands with different band gaps, Eg (orange and red dot-dash lines). c Hall electron concentration, nH dependence of the magnitude of Seebeck coefficient (Pisarenko plot). The inset shows the temperature dependence of nH of two compositions, Ga1 (red circle) and Ga2 (blue circle). d Hall mobility, μH as a function of nH. The red solid line is calculated based on the single Kane band (SKB) model. The inset shows the temperature dependence of μH of Ga1 and Ga2.
