Electronic band structures for Pb(Bi1-xSbx)2Te4 (x = 0.55, 0.70, 0.79). (a) Bulk Brillouin zone and (111) surface Brillouin zone. (b−d) ARPES intensity images along \(\bar{\Gamma}\bar{\rm{M}}\) for x = 0.55, 0.70, 0.79, respectively. Dashed curves represent the projected bulk band edges determined from the calculated bulk bands shown in Fig. 3(a). (e) Constant energy contours of the ARPES intensity x = 0.70 recorded with h ν= 6.994 eV photons.
