联苯分子电导余弦平方关系的验证
Verification of cosine squared relation of electronic conductance in a biphenyl molecule
摘要：
实验获得的（Venkataraman { \em et al}. \cite{latha}）的余弦平方关系的电子电导在联苯分子的紧束缚框架内进行了理论验证。利用格林函数方法，数值计算了两端电导随分子环间相对扭转角的变化关系，结果与实验结果吻合较好。
英文摘要：
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.
