Band structure evolution under strain. (a) The PBE band structures of B9-tKL and B9-KL under strain. Circles indicate three Dirac-like bands, and the bands are color-coded according to their orbital characteristics: green for p z , blue for p x and p y , and red for s orbitals. The spin-down bands are shaded in lighter colors. (b) The HSE06 band structure of B9-KL for spin-up and spin-down electrons, with the spin-resolved density of states on the right panel. (c) The contour plot of the charge density for the flat band near the Fermi level at the K point in B9-KL.
