X-ray photoelectron spectroscopy (XPS) is a surface-sensitive quantitative spectroscopic technique that measures the very topmost 50-60 atoms, 0.01 um, 5-10 nm of any surface. It belongs to the family of photoemission spectroscopies in which electron population spectra are obtained by irradiating a material with a beam of X-rays.

X-ray photoelectron spectroscopy (XPS), also known as electron spectroscopy for chemical analysis (ESCA), is a technique for analyzing a material’s surface chemistry. XPS can measure elemental composition as well as the chemical and electronic state of the atoms within a material.

The XPS Lab has been designed to combine outstanding quantitative XPS performance and ease of operation with a modular sample handling concept. This X-ray photoelectron spectrometer can host complementary surface analytical techniques, like AES and UPS, to enhance its characterisation capabilities.

X-ray photoelectron spectroscopy (XPS), also known as electron spectroscopy for chemical analysis (ESCA), is a highly surface-sensitive, quantitative, chemical analysis technique that can be used to solve a wide range of materials problems.

X-Ray Photoelectron Spectroscopy (XPS) is also known as Electron Spectroscopy for Chemical Analysis (ESCA). X-Ray Photoelectron Spectroscopy is used to determine quantitative atomic composition and chemistry. It is a surface analysis technique with a sampling volume that extends from the surface to a depth of approximately 50-100 Å. XPS ...

2022年11月2日 · Known as one of the most powerful techniques for surface characterization, X-ray photoelectron spectroscopy (XPS) can identify the elements on the surface of a sample and give information on their chemical bonding.

2018年7月7日 · 两年后的1907年，P.D. Innes用伦琴管、亥姆霍兹线圈、磁场半球（电子能量分析仪）和照像平版做实验来记录宽带发射电子和速度的函数关系，他的实验事实上记录了人类第一条X射线光电子能谱。 其他研究者如亨利·莫塞莱、罗林逊和罗宾逊等人则分别独立进行了多项实验，试图研究这些宽带所包含的细节内容。 XPS的研究由于战争而中止，第二次世界大战后瑞典物理学家凯·西格巴恩和他在乌普萨拉的研究小组在研发XPS设备中获得了多项重大进展，并 …
