Description and scientific profile of the group

The Scientific and Practical Materials Research Centre of the NAS of Belarus is a leading research organization in the Republic of Belarus in the field of the condensed matter physics, material science and nanotechnology, which has been created more than 50 years ago. The Research Centre leads two state programs: "Nanomaterials and nanotechnologies" and "Material science and technologies". A direction of the Research Centre functioning covers the creation, investigation and practical application of a broad range of materials (semiconducting, superhard, superconducting, magnetic, etc.) in the form of ceramics, polycrystals, thin films, nanocomposites and heterostructures. The Research Centre regularly carries out international conferences on the actual problems of the solid state physics and on nanomaterials and nanotechnologies. Leading researchers from various countries (USA, Great Britain, France, Germany, Poland, Korea, etc.) take part in these conferences. More information http://www.physics.by/

Research team of the Cryogenic Research Division of the Scientific and Practical Materials Research Centre has more than a 30-year long experience in the field of the creation and investigations of various materials and nanostructures on their base. Members of the team have got a large background in the use of the swift heavy ion track technology for a creation of porous templates on the base of silicon and polymer materials. In this way the Cryogenic Research Division team members have succeeded to create prototypes of the magnetic field sensors, emitters on the base of the carbon nanotubes (on silicon substrates), and microelectronic devices (inductor, transformer and capacitor) based on polymer substrates. Other team activities include investigations of charge transport processes in magnetic multilayer structures; studies of dynamics of desorption and the oxygen nonstoichiometry, cation ordering and electrical properties of double perovskite ceramic compounds; investigations of galvanomagnetic phenomena in cryoconductors based on pure metals in high magnetic fields and liquid helium temperature.

Equipment and Methods

The team has in its disposal the following technical equipment: technological complex for the formation of the SiOx/Si and Six(ON)y/Si templates, containing the latent swift heavy ion tracks; chemical laboratory for the ion tracks etching and the deposition of noble metals and their compositions in nanopores by chemical and electrochemical methods; original inspection of the obtained plasmonic structures, for the optimization of the modes of their obtaining by means of the XRD and SEM (the LEO-1455VP setup); X-ray phase analysis setups; the automated spectroscopic measuring complex which provides a registration of photoluminescence spectra with a high spectral resolution (less than 1 Ǻ ) in a broad temperature range (4.2 - 300 К) and the wavelength region 200-2500 nm; the confocal Raman/photoluminescence spectrometer Nanofinder-HE (LOTIS-TII, Belarus - Japan), which allows one to analyze Raman and photoluminescence spectra of nano- and microstructures; the automated helium liquefier Linde L1410 (USA) is available in the Cryogenic Research Division for the realization of the optical investigations at low temperatures.

Personnel

The research team of the Cryogenic Research Division comprises highly-qualified specialists in the field of condensed matter physics and materials science, including swift heavy ion tracks technology, technology of the synthesis of complex metal-oxide ceramic and single-crystal materials, as well as investigations of their electronic and magnetic properties. The team includes the leading group in Belarus in the field of studies of the optical properties of nanomaterials.
