Electronic band structure and LDOS of (a) CuSbSe₂, (b) CuSbSeTe, i.e., 50% alloying, (c) CuSbTe₂, (d) CuBiS₂, (e) CuBiSSe, 50% alloying, and (f) CuBiSe₂. The energy refers to the VBM (dashed lines). The atom- and angular momentum resolved density-of-states has been scaled with 1/(2l + 1) for better visualization, and it is presented with a 0.20 eV Lorentzian broadening. One can notice the strong Sb/Bi p-like states in the lower energy region of the conduction bands.
