Dear Sir,
I am now studying the tutorial "Bi2Se3 topological insulator" and wanted to download the .py files for learning. However, some of the .py files (such as "bloch_states.py", "fermi_surface.py", "TopologicalInvariant3D.py " ) can only be saved as .html file which can not be displayed correctly in the Editor of ATK package. Because I am a beginner of python, I do not have very clear idea about the organization of the codes. Who can kindly tell me where I can download these .py file?
Thanks a lot!
