The electronic structures of the H-BC5 and H-BC7 sheets. (Color online) The structures, energy bands, and DOSs of (a,c,e) the H-BC5 and (b,d,f) the H-BC7 sheets. The calculated units are delineated by dotted lines, and the spin density distributions are shown in (a,b). The Fermi level is indicated as the line at E = 0 eV.
