A question about band structure silicene by tight binding

[anahita]

Dear forum people,
I know that electronic properties silicene is the same graphene but i can not figure out how can I plot band strcture silicene. I want to plot that in the following path: K→Γ→M→K

You keep talking about PLOTTING the band structure. Do you actually have the analytical form of the band structure and just don't know how to use a software package to plot it? Or what exactly about the "plotting" part that you need help with here?

Without such explanation, this is pretty vague!

Hamiltonian metrix is 8*8. i can not properly calculate elements of the matrix using slater-koster methods. for example overlap between orbitals s and pz is n*v(spσ) but i can't find cosine directions n,l,m.

Ok, this has a bit more information. This is not "plotting". This is the actual calculation to GET the band structure. There's a difference.

Someone who is more up to speed on the silicene band structure calculation may be able to help you.
