Surface band structure
Surface states and resonances (circles) and projected bulk band
structure (blue) along the circular path for
k|| = 0.6 Å-1. |
Dangling-bond band
Contour plot of the band with equidistant (black) and two
additional levels in the Brillouin zone (black frame). The
circular path through the surface band structure
is drawn ingreen. |
Dangling-bond band
3d image of the dangling-bond band (green) and the top of the
projected bulk band structure (blue) in the Brillouin zone. The
vertical direction gives the energy, the circular path is shown
in red. |
Ein = -0.9 eV |
Ein = -0.75 eV |
Surface density of states |
| Polar plots along the
circular path for Ein = -0.9 eV (left)
and Ein = -0.75 eV (right). The radius gives
the value of the surface density of states. |
| Polar plots along the
circular path for Ein = -0.9 eV (left)
and Ein = -0.75 eV (right). The radius represents
the intensity of the photocurrent. |

Patterns are very energy
sensitive when the dispersion of the band is low.
