A way to represent the band structure that distinguishes betweenenergy-momentum and energy-crystal momentum relationships is proposed upon theband-unfolding concept. This momentum-resolved band structure offers betterunderstanding of the physical processes requiring the information of wavefunctions in momentum space and provides a good description of angle-resolvedphotoelectron spectroscopy (ARPES) spectra together with a still informativeband structure. Following this approach, we demonstrate that Dirac cones ingraphene are intrinsically broken in momentum space and can be described by aconceptual unit cell smaller than the primitive unit cell. This hidden degreeof freedom can be measured by ARPES experiments as missing weight that isretrievable by probing the chirality and Berry phases by linearly andcircularly polarized light. Having the energy-momentum relationship, we providealternative understanding of the retrieved momentum intensity, that is, theretrieved momentum intensity is assisted with the properties of final states,not from the Dirac cones directly. The revealed broken Dirac cones and momentasupplied by the lattice give interesting ingredients for designing advancednanodevices.
