Figure 5From: Metal-functionalized single-walled graphitic carbon nitride nanotubes: a first-principles study on magnetic property Calculated electronic structures of the Ti-functionalized g-C 3 N 4 -zz4. (a) spin-up and (b) spin-down band structures, (c) total density of states (TDOS), and (d) partial density of states (PDOS). The Fermi level is at 0 eV.Back to article page
