(color online) ARPES maps and DFT calculations of the electronic structure of 6-layer PdTe2 films. (a) Fermi surface map at photon energy of 21.2 eV. (b) Band structure measured along high symmetry directions. Red dashed lines on the top of photoemission image highlight the Dirac-cone surface state. (c) Calculated surface state of 6-layer PdTe2 film by DFT calculations. Orange line refers to bulk state, while blue line represents surface state. |
