The complex band structures of the CsCl insulator on the Re[k] and Im[k] axes for the selected values of the onsite energy deviation (\(\Delta\)). The first row of the sub-figures (A–D) depicts solutions for the positive values of \(\Delta\), whereas the second row (E–H) presents results obtained for the negative \(\Delta\) values. The propagating, edge and gap states are distinguished by the blue, green and red color, respectively. Moreover, the zero energy level is set at the top of the valence band.
