Brief introductions
Use wannier functions to get the surface state of slab system or edge state of nanowire system or just bulk band. Especially usefull for topological insulator.
Jan 29 2015 at ETH With given hr files from wannier90,
-
There is a Bi2Se3 example in the examples folder. The user guide is in the doc folder. Please read the user guide first.
-
we can get the bulk energy band with given high symmetry kpoint lines.
-
We can get the energy band for slab system when you specify a plane, which can be done by modify ham_qlayer2qlayer.f90. From this calculation, you can get surface state. This is very useful for studying topological insulator.
-
We can get the energy band for nanowire system also.
-
We can get fermi-surface for slab system.
-
We can use iterative green's function to get beautifull surface state.
