[XPS] X-ray Photoelectron Spectroscopy

[XPS] X-ray Photoelectron Spectroscopy

Effective for evaluating the types, quantities, and chemical bonding states of elements on the sample surface (at a depth of about several nanometers).

XPS is a technique that measures the kinetic energy distribution of photoelectrons emitted by X-ray irradiation, providing insights into the types, quantities, and chemical bonding states of elements present on the sample surface (to a depth of about a few nanometers). Because it can provide information about chemical bonding states, it is also known as ESCA: Electron Spectroscopy for Chemical Analysis. - Qualitative and quantitative analysis of elements on solid surfaces (approximately 2 to 8 nm) is possible. - Chemical bonding state analysis is possible. - Non-destructive analysis is possible. - Measurement of depth distribution (using ion sputtering) is possible. - Measurement of insulators is possible. - Measurement under controlled atmospheres is possible.

The influence of adsorbed oxygen in XPS.

The influence of adsorbed oxygen in XPS.

XPS: X-ray Photoelectron Spectroscopy

XPS is a method for obtaining information about the composition and bonding state of the sample surface (to a depth of about several nanometers), but by combining it with ion irradiation for sputter etching, it is also possible to evaluate the internal structure of the sample and depth distribution. However, in evaluations involving sputter etching, due to the principles and measurement mechanisms of XPS, the amount of oxygen may be overestimated due to the influence of adsorbed oxygen, so caution is required. In the case of evaluating samples that easily adsorb oxygen (such as Ti, TiN, AlN, etc.) or focusing on trace amounts of oxygen, the influence of adsorbed oxygen becomes significant, so comparisons between samples and analyses using SIMS are recommended.

[Analysis Case] Verification of Reduction Treatment for Sn Oxide

[Analysis Case] Verification of Reduction Treatment for Sn Oxide

Comparison of XPS and computational simulations: Analysis of electronic states from the valence band spectrum.

XPS is a method for evaluating the composition and bonding state of a material based on the photoelectron spectrum from inner shell levels. On the other hand, the valence band spectrum, which reflects the states of the outer shell electrons, appears near the Fermi level. This document presents a case study that verifies the reduction treatment of Sn oxides by comparing and discussing the density of states calculated through first-principles calculations with the valence band spectrum obtained by XPS. Utilizing computational simulations allows for a deeper understanding of the XPS spectrum obtained.

Application examples of total reflection HAXPES

Application examples of total reflection HAXPES

Under the condition of total reflection, the penetration depth of X-rays is shorter than the escape depth of photoelectrons, so the detection depth of HAXPES is determined by the penetration depth of the X-rays!

Hard X-ray photoelectron spectroscopy (HAXPES) has made significant progress by enabling bulk-sensitive measurements in the hard X-ray region, whereas measurements in the soft X-ray region had been mainstream until now. On the other hand, HAXPES measurements under total reflection conditions of X-rays are also being conducted for the purpose of analyzing surface states. Under total reflection conditions, X-rays are incident at the critical angle for total reflection, which limits the depth of penetration into the material. Applying this characteristic to HAXPES allows for the analysis of bonding states of interfacial oxide layers and segregated impurities at the atomic layer level. *For more detailed information, please refer to the attached PDF document. Feel free to contact us for further inquiries.
