摘　　要：通过控制蒸发源电流、源和样品间距及扩散时间 ,室温下在C60 单晶 (111)解理面上制备出Rb3 C60 。用低温同步辐射角分辨光电子谱测量了样品的能带结构。观察到的能带色散表明样品为单晶薄膜。用X光电子谱首次研究了Rb3 C60 与C60相界面的稳定性。结果表明温度低于约 4 2Rb3C60 thin film was prepared on the (111) surface of C60 single crystal. The energy band structure of the sample was measured at low temperature by using the synchrotron radiation photoemission spectrum technique. The observed band dispersion revealed that the sample was Rb3C60 single crystal film. The stability of the interface between Rb3C60 and C60 was studied for the first time by X-ray photoelectron spectroscopy. The result showed that the interface was stable below about 420 K.
