High symmetry point in GaAs superlattice

  1. Jul 14, 2011 #1
    Hi
    I have a problem that i couldnt solve by myself with my little background. I want to plot the bandstructure for a GaAs superlattice, the z-axis is the 111 direction. The structure is non periodic in the z direction and periodic in the x and y direction. The process is totally different then the bulk situation since that should be a new brillouin zone and a new high symmetry points. I couldnt find the new symmetry points and i couldnt find any good book about this, it is really a big mess for me. so any help will be appreciated.

    Thanks
    Raouf


    NB: I am really new in the field.
