Raman spectroscopy

Raman spectroscopy is a powerful technique in surface technology that makes it possible to obtain detailed information about the molecular composition of materials. This special form of spectroscopy is based on the interaction of light with molecules, whereby inelastic scattering is used to draw conclusions about the vibrational and rotational states of the molecules.

In surface technology, Raman spectroscopy is used in particular to characterize thin layers, coatings and surfaces. The method enables the identification of specific molecules, chemical bonds and structural information without the need for extensive sample preparation.

A significant advantage of Raman spectroscopy in surface technology is that it is non-invasive and allows materials to be analyzed in situ. This is particularly relevant when examining thin layers on substrates, as the analysis process preserves the integrity of the examined surface.

Raman spectroscopy is used in various application areas of surface technology, including the characterization of coatings on microchips, the analysis of layer thicknesses in the semiconductor industry and the investigation of thin films in nanotechnology. By precisely detecting molecular signatures on the surface, Raman spectroscopy enables progress in the development and optimization of materials for a wide range of technological applications.
