This paper describes, firstly, the statistical analysis used to determine the processes that occur during the manipulation of a single molecule through electronically induced excitations with a low temperature (5 K) scanning tunnelling microscope (STM). Various molecular operation examples are described and the ability to probe the ensuing molecular manipulation dynamics is discussed within the excitation context. It is, in particular, shown that such studies can reveal reversible manipulation for tuning dynamics through variation of the excitation energy. Secondly, the photo-induced process arising from the irradiation of the STM junction is also studied through feedback loop dynamics analysis, allowing us to distinguish between photo-thermally and photo-electronically induced signals.
本文首先描述了通过低温（5 K）扫描隧道显微镜（STM）进行电子激发来操纵单个分子时所采用的统计分析方法。描述了各种分子操作实例，并在激发背景下讨论了探测后续分子操纵动力学的能力。特别是，研究表明，通过改变激发能量，可以对动态进行调谐，从而实现可逆的操纵。其次，还通过反馈回路动力学分析研究了来自 STM 结的光致过程，使我们能够区分热光和光电诱导信号。
