Figure 5

Electronic band structure and density of states of the oxygenated Si-rich pSiC surface. We show the electronic band structures (left panel) and densities of states (right panel) of the (a) 3-oxygen and (b) 4-oxygen surfaces; the insets illustrate the corresponding optimized atomic structure models. For the LDOS, the black, green, gray, and red lines represent the contribution of C, Si, H, and O atoms, respectively.
