摘要：我们测量了嵌入在Au{111}表面上自组装的烷基硫醇结晶单分子膜中的单分子和束分子的电子输运性质。用扫描隧道显微镜和微波差频交流扫描隧道显微镜对饱和和完全共轭的分子进行了测量。我们已经学会了分离分子和隧道结的贡献。我们还找到了一种方法来确定由于选择与衬底的化学连接而导致的接触电导值。
ABSTRACT: We have measured the electron transport properties of single and bundled molecules imbedded in crystalline monolayers of alkanethiols self‐assembled on Au{111} surfaces. These measurements have been performed using scanning tunneling microscopy and microwave difference frequency alternating current scanning tunneling microscopy on molecules with saturated and fully conjugated chains. We have learned to separate the contributions of the molecules and of the tunneling junction. We have also found a means to determine the value of the contact conductance due to the choice of chemical connection to the substrate.
