Films comprising the endohedral fullerene Er₃N@C₈₀ are deposited onto highly oriented pyrolytic graphite (HOPG) substrates in high purity enabled by performing mass‐selected low‐energy deposition from a cation beam. In the initial stage, the growth on HOPG is dominated by spontaneous nucleation of small 2D islands both on intact terraces as well as the step edges. The island growth exhibits strong differences from films comprising other fullerenes grown by the same method. This behavior can be explained by the surface‐diffusion‐mediated nucleation model presented in previous work: Dominant components in the behavioural differences are a high intercage dispersion interaction and a lower kinetic energy of cages migrating on the surface in comparison with previously deposited materials. When annealed, the films undergo several competing processes: A small fraction desorbs in the temperature range 700–800 K, another fraction forms covalent intercage bonds instead of the previous purely dispersive bonding mode, and a third fraction probably decomposes to small fragments.

高纯Er3N @ C80膜：形貌，光谱表征和热稳定性

包含内膜富勒烯Er ₃ N @ C _80的薄膜通过从阳离子束中进行质量选择的低能沉积，可以高纯度地将其沉积到高度定向的热解石墨（HOPG）基底上。在初始阶段，HOPG的生长主要是在完整阶地和台阶边缘上的小二维岛的自发成核。岛的生长与通过相同方法生长的包含其他富勒烯的薄膜显示出很大的差异。可以通过先前工作中提出的表面扩散介导的成核模型来解释这种行为：与先前沉积的材料相比，行为差异中的主要成分是高的笼间分散相互作用和较低的笼子在表面上迁移的动能。退火后，这些膜会经历几个竞争过程：
