Band dispersions of SmB6(111) around the Fermi level. ARPES data were taken with the same condition as Fig. 2. a ARPES intensity plots along \({\bar{\mathrm{\Gamma }}} - {\bar{\mathrm{M}}}\) symmetrised with respect to \({\bar{\mathrm{\Gamma }}}\) (k = 0 Å−1). ARPES intensities are divided by the Fermi distribution function convolved with the instrumental resolution. b, c ARPES b momentum distribution curves (MDCs) and c energy distribution curves (EDCs) taken from the 2D data shown in (a). Triangle markers indicate the peak positions. The open triangles with error bars in (c) are the energy positions of broad features. The width of the bars is explained in the text. d 2D plot of the peak positions in (b, c). The bars with open triangles are the same as those in (b). The shaded area in the left side is the projected bulk bands from ref. 27. Fat curves are the traces of the peak positions. These curves are copied on (a)
