Russian Physicists' Research Might Lead to a New Generation of Microprocessors
Anatoly Zatsepin's (Ural Federal University, Ekaterinburg, Russia) report on the physics of condensed states was noted by the global scientific society.
- (1888PressRelease) November 03, 2017 - Anatoly Zatsepin, head of the laboratory named "Photonics and VUV Spectroscopy" of the Department of Physical Methods and Instruments of Control (Institute of Physics and Technology, Ural Federal University, Ekaterinburg, Russia) received a special certificate for his public presentation of the research at a congress in Valencia, Spain. The scientist's report was devoted to fundamental studies of oxides of rare-earth elements with reduced dimensionality. The objects of research raise interest of the scientific society as they can be used as new materials with predetermined properties for devices converting UV and IR radiation. In the long run, the research may lead to creation of a new generation of microprocessors which are dozens of times faster and smaller than the existing ones.
The congress, which was organized by the International Scientific Federation, brought together more than 300 participants from Spain, France, Italy, the USA, Great Britain, Japan, India and other countries.
"The audience received my report with great interest and were really impressed by some of the results we had achieved," said Anatoly Zatsepin. “In the course of studies of gadolinium oxide nanoparticles, we discovered the so-called ‘giant softening effect of optical phonons’. We managed to create conditions under which the energy of UV and IR radiation absorbed by these nanoparticles can be converted into visible light with maximum efficiency. At the same time, the energy losses, which inevitably exist, turned out to be an order of magnitude lower than they should be in theory."
According to Anatoly Zatsepin, the effect has been repeatedly checked and confirmed. Such result allows to achieve an increase in efficiency of long-range space communication systems, complex integrated chips, in the creation of new generation microminiature nanolaser, which will be in demand in both medical and biological studies and in practical medicine. At the moment, scientists of the UrFU Institute of Physics and Technology are developing a theoretical model which could adequately describe the results.
The project for the study of rare earth oxides with reduced dimensionality has already received support from the Ministry of Education and Science of the Russian Federation. It is planned that the state will be supporting the project for three years. The project involves young employees, postgraduates and students of several departments of the UrFU Institute of Physics and Technology.
"I would like to underline that these achievements were the result of a young researchers team’s work. A post-graduate student of the department, Yulia Kuznetsova, made a significant contribution to the experiments, data processing and preparation of materials. Her diploma project gave impetus for the research; we started developing this field and received support from the Ministry of Education and Science of the Russian Federation, established contacts with leading Russian and foreign researchers," said Anatoly Zatsepin.
