论文摘要
扫描 - 微镜诱导的发光是最近出现的，是一种尖锐的工具，可将分子特性降低到单分子水平。快速的实验进步与理解观察到的现象的理论努力相去甚远。这种无能导致在定量分配荧光光谱的特征到单个分子的结构和动力学方面的特征。该字母致力于通过扫描隧道显微镜中的隧道电子的非弹性散射来揭示分子激发的显微镜起源。当前的理论解释了观察到的在正和负偏置电压下的分子发光强度之间的较大的光子计数不对称性。
The scanning-tunneling-microscope-induced luminescence emerges recently as an incisive tool to measure the molecular properties down to the single-molecule level. The rapid experimental progress is far ahead of the theoretical effort to understand the observed phenomena. Such incompetence leads to a significant difficulty in quantitatively assigning the observed feature of the fluorescence spectrum to the structure and dynamics of a single molecule. This letter is devoted to reveal the microscopic origin of the molecular excitation via inelastic scattering of the tunneling electrons in scanning tunneling microscope. The current theory explains the observed large photon counting asymmetry between the molecular luminescence intensity at positive and negative bias voltage.
