Is it possible to plot a 2D Fermi surface while assigning weights to specific tags, similar to how fat band structures are visualized? For instance, if the surface and bulk states are tagged in the configuration, can these tags be used to indicate their respective contributions to the bands in the Fermi surface plot? I have already generated a 2D Fermi surface plot (ka vs kb), but I would like to differentiate between the contributions from bulk and surface states.
