Fig. 6. The projected density-of-states (PDOS) for (a) free standing N₃(CH₂)₃S and (b) N₃(CH₂)₃S adsorbed on ZnO(101̄0). The red and gray areas represent the contribution of the surface O and Zn atoms, respectively on the surface. The Fermi level (E_F) is indicated by the dashed vertical line at 0 eV.
