C60单分子电子输运的动态Jahn-Teller效应
Dynamic Jahn-Teller effect in electron transport through single C60 molecules
摘要：
扫描隧道光谱上的单个C60分子，充分去耦从基板表现出一个特征的精细结构，这是由于动态Jahn-Teller效应解释。利用从密度泛函理论中提取的电子-声子耦合，我们计算了通过C60-阴离子态的隧穿谱，发现与测量数据非常吻合。
英文摘要：
Scanning tunneling spectra on single C60 molecules that are sufficiently decoupled from the substrate exhibit a characteristic fine structure, which is explained as due to the dynamic Jahn-Teller effect. Using electron-phonon couplings extracted from density functional theory we calculate the tunneling spectrum through the C60- anionic state and find excellent agreement with measured data.
