Verification of cosine squared relation of electronic conductance in a biphenyl molecule
arXiv:1306.3752 · doi:10.1016/j.physe.2014.03.028
Abstract
The experimentally obtained (Venkataraman {\em et al}. \cite{latha}) cosine squared relation of electronic conductance in a biphenyl molecule is verified theoretically within a tight-binding framework. Using Green's function formalism we numerically calculate two-terminal conductance as a function of relative twist angle among the molecular rings and find that the results are in good agreement with the experimental observation.
