论文摘要
我们提出了一种用于分析扫描隧道显微镜（STM）固定检测区域中单分子的停留时间的理论。该方法是针对一维分子扩散而开发的，可以使用相同的方法扩展到两个维度。明确的结果是针对谐波吸引力和排斥的尖端 - 分子相互作用的。该理论的应用允许人们估计STM尖端与分子之间相互作用的类型和强度。这包括当尖端通过分子装饰时估计分子 - 分子相互作用的可能性。尽管我们专注于STM，但该理论可以类似地应用于监测单分子的其他实验探针。
We present a theory for analyzing residence times of single molecules in a fixed detection area of a scanning tunneling microscope (STM). The approach is developed for one-dimensional molecule diffusion and can be extended to two dimensions by using the same methodology. Explicit results are derived for an harmonic attractive and repulsive tip-molecule interaction. Applications of the theory allows one to estimate the type and strength of interactions between the STM tip and the molecule. This includes the possibility of an estimation of molecule-molecule interaction when the tip is decorated by a molecule. Despite our focus on STM, this theory can analogously be applied to other experimental probes that monitor single molecules.
