Elemental Analysis of the Solid Surface

Photoelectron Spectroscopy: X-ray (XPS) and Ultraviolet (UPS) Spectroscopy

Objects of study

Solid samples.


By XPS method are determined:

  • Chemical composition of the surface – all the elements starting from Li are detected.
  • Electron state of the substance components.
  • Relative component concentration in the sample.

UPS method - for conductors and semiconductors:

  • High resolution analysis of the electron structure of the surface valence band.

Additional possibilities

  • Study of the surface state under the reaction conditions at the pressure up to 10–2 mbar - this is a unique study in the world practice.
  • Application of XPS, UPS simultaneously with such methods as in situ thermal desorption, kinetic measurements, low energy electron diffraction (LEED) to study the structure of adsorbed layers.
  • Availability of a large set of procedures for sample supporting and spectra calibration.
XPS with angle resolution for study of chemisorbed layers.

Instrument facilities

Electron spectrometers VG ESCALAB HP and VG ESCA-3 (“Vacuum Generators”, Great Britain), ES-300 (“Kratos”, Great Britain). For X-ray generation MgKa and AlKα lines with hγ = 1253.6 eV and 1486.6 eV are used, respectively.

Samples requirements

Solid samples of any morphology in the form of plates, powders, chips and others. The plate size is not less than 6x6 mm2, not higher than 12x12x2 mm3. The samples must not be destructible in vacuum.
