Reproducible negative differential resistance (NDR)-like switching behavior is observed in NanoCells. This behavior is attributed to the formation of filaments and clusters between the discontinuous gold films. Control experiments are performed by self-assembly of insulating molecules between the gold islands and conducting molecules on these islands. Additional control experiments are performed by removing the filaments and clusters between islands using a piranha bath. The results are consistent with theoretical predictions and extend the domain of molecular electronics based in organic molecules to include nanosized clusters as active units. This facilitates a scenario where synthetically accessible organic molecules, with defined characteristics, can be adjusted by metallic nanoclusters as an in situ fine-tuning element, able to compensate for the lack of addressing in the nanosize regime.
在纳米电池中观察到了类似可重复负微分电阻(NDR)的开关行为。这种行为归因于不连续金膜之间细丝和团簇的形成。通过在金岛之间自组装绝缘分子以及在这些岛上的导电分子来进行对照实验。另外,通过使用王水去除岛之间的细丝和团簇来进行对照实验。结果与理论预测一致,并将基于有机分子的分子电子学领域扩展到包括纳米尺寸团簇作为活性单元。这促进了一种情况,即具有确定特性的可合成获取的有机分子可以通过金属纳米团簇作为原位微调元件进行调节,能够弥补纳米尺寸体系中寻址的不足。
