Surface state of LnPn. a, b Band structure of a semi-infinite [001] surface of a topologically non-trivial CeBi and b topologically trivial YbSb using (Heyd–Scuseria–Ernzerhof hybrid) HSE06. c–e Surface state of semi-infinite [001] surface of CeBi using HSE06 at c EF, d EF − 0.1 eV, and e EF − 0.2 eV. The zone center is Γ, whereas the corners are X. The bulk states can be identified with continuum-like spectrum, while the surface states appear as individual lines. In c, the α, β, γ1, and γ4 pockets are indicated
