Energy-dispersive X-ray spectroscopy (EDS, also abbreviated EDX or XEDS) is an analytical technique that enables the chemical characterization/elemental analysis of materials. A sample excited by an energy source (such as the electron beam of an electron microscope) dissipates some of the absorbed...
EDS分析是利用元素的特征X射线，而氢和氦原子只有K层电子，不能产生特征 X 射线，所以无法进行成分分析...
We have also carried out detailed energy dispersive X-ray spectroscopy analysis along a number of crystal layers, obtaining atomic percentages along these layers. With simple, plausible assumptions, we have found the phase amounts along the crystal layers. The process of analysis is repeated for ...

XPS是用已知固定波长(即固定能量)的X射线(X-ray)轰击样品,把样品中原子里的电子撞出来,然后测量撞出电子的动能以及拥有某一动能值的电子数。这样我们可以得到一个能谱图。通过测量入射X-ray与图中峰值对应的动能之差,我们可以确定样品原子中电子的结合能(bindingenergy)。然后可以查一查这个结合能与哪种元素电子的...
