URFA Photonics and VUF-spectroscopy

At the beginning of 2017 scientists of Ural Federal University (URFA) announced the researches allowing to create computer processors which in several tens of times will have bigger high-speed performance and the smaller sizes in comparison with processors of today. In creation of new technologies basic researches of oxides of rare-earth elements with the lowered dimension should bring break.

The project is directed to creation of new materials with the set properties for conversion devices of radiation of UF and Infrared ranges. From that, how successfully scientific it will be possible to achieve efficiency of such conversion, and the project success depends.

The main objective of scientists consists in obtaining detailed information on features of formation of power structure, the nature and dynamics of excited states, mechanisms of migration and dissipation of energy in razuporyadochenny and low-dimensional oxides of rare-earth elements.

According to the head of "Photonics and VUF-spectroscopy" laboratory of department of physical methods and devices of control of FTI Anatoly Zatsepin, the relevance of an assigned task decides by a possibility of creation of new generation of functional structures on the increased efficiency and high-speed performance for devices of nanophotonics, optoelectronics, alternative power engineering and microsystems of conversion of electromagnetic radiations. The innovative technologies will help to create devices of new generation with high efficiency, high-speed performance for conversion, storage and information processing. In addition to chips for computers and phones, the latest lasers, LEDs, displays, sensors, converters and solar cells with the advanced characteristics can be also created.

"As objects of a research nanopowders, ceramics, the thin films of RZE oxides, solid solutions and nanocomposites received by methods of ion-beam technologies are selected — Anatoly Zatsepin told. — The feature of methodical approach which will be implemented in work consists in system application of a complex of experimental and theoretical methods within a uniform closed loop "synthesis — deficiency — electronic structure — functional property — a device prototype".

During the researches scientists URFA use modern methods x-ray, optical, photoelectronic, EPR, IK and KR-spectroscopy. According to Anatoly Zatsepin, it will allow to determine parameters of local atomic structure, feature of defect formation, power and kinetic characteristics of excited states in systems supporting optically the active centers, clusters and quantum points. It is also very important to understand specifics of donor and acceptor interactions and pattern so-called the wanker - and ap-conversion transmission of energy.

"The analysis of data retrieveds will provide understanding of mechanisms of electron-optical processes at the microlevel that will allow to modify defective structure and parameters of the studied materials in relation to a problem of conversion of radiations. As a result, on the basis of the synthesized thin-film heterostructures it is supposed to create a prototype of new conversion UF and IK of transformers, to test, optimize characteristics and to formulate technology recommendations" — Anatoly Zatsepin noted.

The head of laboratory also explained why as objects for a research rare-earth oxides with the lowered dimension were selected. He is sure that at the moment these materials are studied insufficiently well as perspective converters of radiations of new generation, and the purpose is in realizing the potential which is available in them. So far in the course of conversion of one type of radiations to radiations of other range there are big power losses therefore the task consists in that on the basis of new detailed information on physics of the phenomenon to learn to manage efficiency of the specified conversion.

"Low-dimensional objects of this kind allow us to solve this problem quite successfully, and we are configured on the fact that as a result of researches prototypes of new functional devices with the increased power conversion efficiency and, the most important, high-speed performance will be created" — Anatoly Zatsepin told.

The project of a research of oxides of rare-earth elements with the lowered dimension already got support of the Ministry of Education and Science of the Russian Federation. It is planned that the state support of the project will be performed within three years. The young staff, graduate students and students of several departments of Physicotechnological institute URFA participate in the project.
