GROUP THEORY SYMBOL

# GTBZLines

GTBZLines[kpath,kplist]

generates **k**-points along a set of lines defined in the Brillouin zone. kplist defines the number of points used for each part of the path.

## DetailsDetails

- Electronic or phontonic band structures are usually calculated along a certain path in the Brillouin zone. GTBZLines generates such paths. kpath is a list containing the symmetry points of the path and the names of the symmetry points. If standard paths for a certain Brillouin zone are used, those lists can be generated by GTBZPath. kplist contains the number of
**k**-points in each part of the path, i.e. between two symmetry points. - The output is used in GTBandStructure to plot the corresponding band structures.
