LDOS and PDOS of (a) H-passivated and (b) graphitic-like reconstructed C(331) surfaces. The zero energy corresponds to the FL. The peak near the FL in the LDOS curve of (b) is associated with the localized electronic states at the surface and subsurface regions, which may have a significant impact on the surface conductivity.
