        Effects of metal-molecule interface conformations on the electron transport of single molecule

        Ping Bai,Er Ping Li,Chee Ching Chong,Zhikuan Chen 한국물리학회 2006 Current Applied Physics Vol.6 No.3

        The electron transport eects of molecule locations on the metal interface are investigated through metalmoleculemetal systemsusing the rst principles method, based on density functional theory with norm conserving non-local pseudopotentials and non-equilib-rium Green’s functions. Three kinds of moleculemetal interface conformations are studied. These include locating the molecule on thetop, at the hollow site and on the bridge of metal surface atoms. AumoleculeAu open systems are constructed and numerically exam-sion functions of constructed systems are calculated and analyzed. Simulated results show that the on-atom contact exhibits the bestmoleculemetal coupling when an external bias lower than 1.4 V is applied. The bridge contact has a similar coupling as the hollow con-tact with a small dierence at larger external bias. This may partially explain why experimental results have poor repeatability.
