I'm sure this is well known to those who know, but how can I extract the surface band structure from a slab calculation?
More specifically, I dealing with 10-12 layer slabs, seperated by vacuum. What do I put into the block "BandLines" to get the surface BZ, i.e the projection of the bulk BZ in the direction perpendicular to the surface? If I have the surface in the (x,y) direction, for example, how would I then set the z value of the vectors in "BandLines"? I'm guessing it's the same as the 1st BZ edge in that (z) direction, but I'm guessing... With thanks Ian Shuttleworth
