a Top and side view of crystal structure of 8 Pmmn borophene. The gray and faint teal circles denote inner (I) and ridge (R) boron atoms, respectively. b Density functional theory with Perdew-Burke-Ernzerhof parameterization (DFT-PBE) band structure of pristine 8 Pmmn borophene and (c) its three dimensional reconstruction. d First Brillouin zone and decomposition of elementary band representation the 8 Pmmn group. The ± are the eigenvalues of \({\tilde{C}}_{{{{{{{{\rm{2x}}}}}}}}}\), and \({\tilde{C}}_{{{{{{{{\rm{2y}}}}}}}}}\) operations at high-symmetry points. e The orbital-projected band structures for two atoms of 8 Pmmn borophene based on DFT-PBE. The Fermi energy (EF) is set to the zero energy.
