(a) BZ of hexagonal Bi2Se3 where we mark the time reversal invariant momenta Γ(000), L(π,0,0), F(π,π,0) and Z(π,π,π). (b) FS of CuxBi2Se3 for doping x=0.16. A colour (magenta positive, cyan negative) corresponds to a proposed p-wave solution for the superconducting energy gap of the A2u symmetry discussed in text.
