The photocurrents from selected spatial areas are calculated for the
full hemisphere with the polar angle of 90° at the border of the spheres,
Ein = -4.0 eV and Efin = 17.0 eV.
The black lines show the Brillouin zones. The color
table is valid for all partial currents but
different from that used for the total current in the top left image
(there: low=black-green-red-violet-white=high).
The pictograms indicate the considered regions. Black are atoms and
bonds, the blue shading gives the considered areas. The vacuum begins above
the surface atoms depicted in the pictograms.
Two bonding zigzag chains dominate the shown photocurrent pattern.
Full hemisphere patterns can be
dominated by electrons from distinct bonds.
