利用扫描隧道显微镜研究了C60分子的单电子隧穿效应与离散分子能级之间的相互作用。分离的C60分子沉积在金基底上，由薄绝缘层覆盖。孤立分子的隧穿电流-电压特性，无论是在室温下，在4.2 K，表现出丰富的结构，导致从充电效应和电子光谱之间的相互作用。特别是，我们观察到C60分子轨道内的简并提升，可能是由于Jahn-Teller效应和局部电场。
The interplay between single electron tunneling effects and the discrete molecular levels of C60 molecules is studied using scanning tunneling microscopy. Isolated C60 molecules were deposited onto a gold substrate, covered by a thin insulating layer. The tunneling current–voltage characteristics of isolated molecules, both at room temperature and at 4.2 K, exhibit rich structures, resulting from the interplay between charging effects and the electronic spectrum. In particular, we observe degeneracy lifting within the C60 molecular orbitals, probably due to the Jahn–Teller effect and local electric fields.
