Electronic Bands and Fermi Surfaces
The bands for antiferromagnetic superconductor having electrons are given in figure.
Near the Fermi energy the states consist mainly of Fed and
As orbitals. They are colorcoded lighter for states and darker for states
a Circle the crossing points at the Fermi energy on band plot for
b ONLY for the plane, ie mark those points for in the BZ square
provided and then sketch the Fermi surface connect the points known to define the surfaces
c Label curves in the bands at crossing points with # or # character, noting
that is possible, depending on direction in space, for an arc along to vary in character.
d For any pockets found, state whether they are "hole" or "electron" pockets?
