Equipment

The Department of Experimental Physics has at its disposal a number of devices and other facilities that are primarily used for scientific and educational purposes, but they are also available for contractual, commercial measurements, etc. Below there is a list of the devices that are not quite common and on which, in the case of interest, we offer the possibility of commercial measurement or scientific cooperation.

In the case of interest in the measurement, contact the person who is in charge of the instrument or the Head of the Department. In most cases it is necessary to carry out preliminary measurements at the beginning of the cooperation for verification of the suitability of the method and. This service, even in the case of commercial measurements, is free of charge.


Microscopes

Scanning Electron Microscope Tescan VEGA3

The apparatus is designed for observing small samples or small details on the sample. The smallest observable objects can be about 10 nm large. It is typically used for measurements that are not sufficient for the resolution of optical microscopes, but may have other benefits, such as greater depth of field or other source of contrast. Electron lithography can also be performed on the microscope.

Spectroscopes

Mössbauer Spectrometer

Mössbauer spectroscopy allows determination and quantification of the phase composition of iron-containing substances (amorphous, nano-crystalline); furthermore, it allows to determine of valence and spin states of atoms under investigation, to distinguish structural positions of the atoms, to determine magnetic states and local configuration of magnetic moments of the atoms; determine magnetic properties including thermal and magnetic transitions; study the mechanisms and kinetics of solid state reactions, phase transformations.

The method serves as a basic or supportive method in materials physics, nanotechnology, metallurgy, chemistry, archeology, geology, mineralogy, etc.
