X-ray photoelectron spectroscopy (XPS) is a surface-sensitive quantitative spectroscopic technique that measures the very topmost 200 atoms, 0.01 um, 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.

From non-stick cookware coatings to thin-film electronics and bio-active surfaces, X-ray photoelectron spectroscopy instruments are the standard tools for surface characterization. Choosing the right XPS solution for your research is no easy feat.

XPS is typically accomplished by exciting a samples surface with mono-energetic Al kα x-rays causing photoelectrons to be emitted from the sample surface. An electron energy analyzer is used to measure the energy of the emitted photoelectrons.

2022年5月18日 · X-ray photoelectron spectroscopy is one of the most widely used surface-sensitive electron emission spectroscopic techniques. Its development is based on the photoelectric effect, which may detect the element existing within a …

X-ray photoelectron spectroscopy (XPS) enables surface analysis, providing elemental composition as well as the chemical and electronic state of the top 10 nm of a material. With depth profiling, XPS analysis extends to compositional insight of layers.

2023年7月4日 · X-ray photoelectron spectroscopy is a surface-sensitive analytical technique that involves bombarding a material’s surface with X-rays and measuring the kinetic energy of the released electrons.

The PHI Genesis is the latest generation of PHI’s highly successful multi-technique XPS product line with PHI’s patented, monochromatic, micro-focused, scanning X-ray source.
