英文摘要	金属/分子/金属结是分子电子学中的基本单元.根据电子的相位是否发生改变,分子结中的电子输运可以分为相干输运和非相干输运两类.在实验上,分子结的表征方法可以分为电学性质表征和非电学性质表征两类.本文借助能级图,首先对分子结的电子输运机理作了简明解释.在此基础上,结合文献报道和本课题组此前的工作,对分子结的一些常用电学表征方法,包括电流-电压特性曲线、电流-时间曲线、电导统计柱状图、转变电压谱、散粒噪声测试、非弹性电子隧道谱和热电效应法进行了介绍.; Although molecular electronics emerged several decades ago,it is still concerning about fundamental issues so far.Metal/molecule/metal junction is a conceptually basic unit in molecular electronics.The mechanism of electron transport through metal/molecule/metal junction has attracted great interest.In general,the mechanisms for electron transport through metal/molecule/metal junctions can be divided into two categories: coherent transport and non-coherent transport according to the phase change of tunneling electrons.In this review,the electron transport mechanism is illustrated briefly by employing energy diagrams.Moreover,several extensively measured approaches for studying metal/molecule/metal junctions,including I-V characteristic curve,I-t trace and conductance histogram,transition voltage spectroscopy,shot noise,inelastic electron tunneling spectroscopy,and thermoelectricity are introduced through referring to some recent publications including our works.; 科技部-国家重大科学仪器设备开发专项项目(批准号:2011YQ030124); 国家自然科学基金(批准号:21321062;21373172)资助~~
