Fig. 4: The band structure characterizations of DDA-Cu film.
From: A one-dimensional conductive metal-organic framework with extended π-d conjugated nanoribbon layers
a The UPS spectroscopy of DDA-Cu. b The LEIPS spectroscopy of DDA-Cu. c The electrical band gap characterization combined by UPS and LEIPS. d A view of the Brillouin zone paths used in the DFT calculations. e The band structure (the left part) and density of states (the right part) for DDA-Cu by HSE06 method. The Fermi energy has been corrected to 0 eV. The orange and blue branches correspond to spin-up and spin-down bands in the band structure, respectively. For the density of states, the arrow up represents the spin-up part and the arrow down represents the spin-down part. Source data are provided as a Source Data file.
