## Description

- description: Electronic band structures in hydrogenated graphene are theoretically
    investigated by means of first-principle calculations and an effective tight-binding
    model. It is shown that regularly designed hydrogenation to graphene gives rise
    to a large band gap about 1 eV. Remarkably, by changing the spatial pattern of
    the hydrogenation, topologically distinct states can be realized, where the topological
    nontriviality is detected by C2 parity indices in bulk and confirmed by the existence
    of gapless edge/interface states as protected by the mirror and sublattice symmetries.
    The analysis of the wave functions reveals that the helical edge states in hydrogenated
    graphene with the appropriate design carry pseudospin currents that are reminiscent
    of the quantum spin Hall effect. Our work shows the potential of hydrogenated
    graphene in pseudospin-based device applications.
