The in-plane k x - k y map at E = -0.65 eV, taken with 200 eV photons (corresponding to k z ~ 0.5 c * ). The black hexagons in ( e ) and grey rectangles in ( f ) label the BZ boundaries. The surface BZ for (001)-oriented CrSb, which is the projection of three-dimensional BZ onto the (001) surface, is labelled in ( e ) with the high-symmetry points , and . The color bar for image plots in ( e , f ) is indicated.
