Homework Help: Tight Binding Hamiltonian for Graphene

Tags:
  1. Sep 25, 2011 #1
    Hello, I am trying to write a program that will automate the creation of a tight binding Hamiltonian matrix for armchair cut graphene. However, I have almost no experience coding and would need some help to get started.

    This would be assuming that the energy between nearest neighbor carbon atoms is t and everything else zero.

    The only real info I have gathered myself is that for an armchair configuration, the number of atoms along a straight x or y line will be even. (as opposed to zigzag which would be odd).

    Does anyone have any tips for me or examples of this being done?

    Thank you very much!

    P.S. I have a copy of Maple and would ideally like to use that as opposed to matlab, mathematica, etc
