Verification of cosine squared relation of electronic conductance in a biphenyl molecule
Abstract
The experimentally obtained (Venkataraman et al. 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.
