用芯能级电子能量损失谱研究了Co/Si（111）界面E F以上的空态密度。除了Co的L2，3吸收边外，还记录了第一扩展能量损失精细结构。它提供了深入了解界面的局部顺序。界面的电子和结构性质与体Co的那些的比较清楚地表明在低覆盖范围内在Co/Si（111）界面处形成各种硅化物化合物。
Core-level electron-energy-loss spectroscopy has been applied to investigate the density of empty states above E F of the Co/Si (111) interface. Besides the Co L 2, 3 absorption edges, the first extended energy-loss fine structure has also been recorded. It gives insight into the local order of the interface. The comparison of both electronic and structural properties of the interface with those of bulk Co shows unambiguously the formation of various silicide compounds at the Co/Si (111) interface in the low coverage range.
