采用三种不同的表征方法研究了不同长度的烷基乙氧基化物自组装单分子膜的室温电荷输运特性，其中横向面积从纳米到微米尺度。在每种方法中，测量的电流-电压特性与金属-绝缘体-金属隧道模型进行了分析。在可能的情况下确定运输参数，并在不同方法之间进行比较，以及与先前报告的值进行比较。每种方法的优点和局限性，表征分子路口突出。
Room-temperature charge transport is investigated for various-length alkanethiol self-assembled monolayers using three different characterization methods, in which lateral areas span from the nanometer to the micrometer scale. In each method, the measured current-voltage characteristics are analyzed with metal-insulator-metal tunneling models. Transport parameters are determined where possible and compared across methods, as well as to previously reported values. Advantages and limitations of each method for characterizing molecular junctions are highlighted.
