A Mechanical properties graphene nanoribbons

  1. Jun 8, 2016 #1
    Hi
    In calculation the mechanical properties of graphene nanoribbons by tight binding methods should band structure graphene calculated by the DFT and tight binding methods fitted to calculate b parameter. In the tight binding methods hopping parameter changes as follow:
    t'_{ppsigma}=t_{ppsigma} exp(-b{l/a0 - 1)) .
    Can help me for calculate b??
