X-ray photoelectron spectroscopy enables XPS surface analysis, providing elemental composition and the chemical/electronic state of the top 10 nm of a material.
What is X-ray photoelectron spectroscopy (XPS)? XPS can measure the elemental composition, empirical formula, chemical state, and electronic state of the elements within a material. XPS spectra are obtained by irradiating a solid surface with a beam of X-rays while simultaneously measuring the kin...

X-ray photoelectron spectroscopy (XPS), also known as electron spectroscopy for chemical analysis (ESCA), and Auger electron spectroscopy (AES) are widely used materials characterization techniques belonging to the general class of methods referred to as surface analysis. These non-destructive techniques...
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...
