4)背散射电子能量损失谱:确定样品表面H元素的含量; 5)角分辨XPS:无损得到样品表面约 10 nm 深度内元素及其化学态随深度的分布信息; 6)原位实验:样品可做变温实验,加热最高温度至1000 k,冷却最低温度至100 k,对同一位置进行测试分析,Ar离子团簇/单离子可清洁表面。 五、送样要求 1)薄膜样品:样品表面平整干净,...
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...
我们为什么说ESCA,是XPS的另一种形式,电子光谱的化学分析,我们用XPS是为了分析样品表面的化学环境,化学分析,所以ESCA它对应的就是最早期的XPS,虽然他们的符号不一样,但是意义是一样的。这是X射线从我们腔体出发,打到样品表面,然后会产生光电子,电子是怎么来的? 3楼2023-10-15 07:19 回复 _奈文摩尔 光子的...
