“…The estimated band gaps of graphyne-like families (monolayer, bilayer, multilayer, nanotubes, and nanoribbons) with and without strain by different functionals are compiled in Table 2 . A wide range of band gap levels were found for γ -GY [ 121 , 122 , 123 , 124 , 125 , 126 , 127 , 128 , 129 ] and γ -GDY [ 42 , 106 , 121 , 125 , 126 , 127 , 130 , 131 , 132 , 133 , 134 ] (0.447–2.23 eV for γ -GY and 0.44–1.21 eV for γ -GDY), which is strictly related to the applied calculation functionals, as reviewed in Table 2 .…”

“…The effect of dopant distribution and functional groups on adjusting the electronic or magnetic properties of GYs might lead to new promising electronic, optoelectronic, and spintronic devices. The calculations revealed that unmodified γ-graphyne is a nonmagnetic semiconductor [ 128 ], while the adsorption of transition metal (TM) atoms might drastically change the electronic structure of and add ferromagnetic features to GY nanostructures [ 163 , 164 ]. In 2012, He et al theoretically investigated (DFT + U) the electronic structure and magnetism of GDY and GY doped with single 3 d transition metals (V, Cr, Mn, Fe, Co, and Ni) [ 164 ] The adsorption of metal atoms on the GDY and GY surfaces generated charge transfer between metallic adatoms and polymeric sheets.…”

“…In order to search out the most stable metal atom (M) decorated 2MLBP structure, the formation energy ( E f ) of the decorated structure with the metal atom located at four different positions is calculated as follows: , Here, E P , E M , and E 2MLBP‑M are the total energy of the isolated P, metal, and metal decorated 2MLBP respectively. N P is the total number of P atoms in metal-doped 2MLBP.…”

“…The E f can reflect the stability of a structure. The positive value means an exothermic reaction, a more stable structure should have a lower E f . , On the basis of the research proved by Yang et al, four different doping positions for the metal atom have been considered, as shown in Figure . They are, respectively, as follows: (a) replacing one P atom on the surface; (b) replacing two P atoms on the surface; (c) in the middle of up and down layers of 2MLBP; (d) bonding to three dangling P atoms on the surface of 2MLBP.…”

“…[40] Especially in the case of GDY,t he existing of abundanta cetylenic bonds can provide more doping sites for av ariety of heteroatoms,w hich makes the situation more complex. Until now,t heoretical calculation work has verified that various of heteroatoms can be selected for the doping on GDY including non-metal heteroatoms (hydrogen, [41] boron, [42] silicon, [43] nitrogen, [44] phosphine, [45] fluorine, [46] halogen atoms [47] ), metal atoms( aluminium, [48] germanium, [49] some transition metals, [50] noble metal [51] )a nd hybrid atoms (boron/nitrogen, [52] nitrogen/sulfur [53] ).…”
