Bogdan physics biography

It is thanks to the achievements of acoustoelectronics that we have small cell phones, navigation systems, cable television. Acastooptic modulators, filters, deflectors are used in medicine, laser physics, optoelectronics, environmental control. Sergey Vasilievich Bogdanov 2. Photo author: Viktor Yakovlev Sergey Vasilievich Bogdanov arrived in Novosibirsk in the year, in the newly created institution of semiconductor physics, at the invitation of its founder and first director of academician A.

before that, S. Bogdanov worked at the Physical Institute. Sergei Vasilievich was studying acustoelectric and acustooptic effects, or, as they are called otherwise, electron-phonon interactions in the crystal. The most striking works of S. Bogdanov are associated with acoustoopics and strengthening of ultrasound in the layered structure of the semiconductor-prezoelectric.

For the creation of the physical foundations of the acustopian, Sergei Vasilievich Bogdanov, as part of the team of authors, received the USSR State Prize in the field of science and technology in the year. Bogdanov created a complete physical picture of phenomena occurring in piezokerism, laid the foundations of a new scientific direction in the physics of the solid body - physics of ceramic piezoelectric elements.

Ceramic piezoelectric elements are widely used in ultrasonic flaw detector, hydroacousticity and other areas. Studies by S. Bogdanov, which he led in Fiana, belonged to the study of the properties of a segotoelectric barium titanate. Barium titanate is now used in the manufacture of integrated microcircuits, capacitors, excitements, electro -optical modulators and other microelectronic devices, and at that time it was pioneer.

At the Institute of Physics of Semiconductors, the subject of research by Sergey Vasilievich has changed and was devoted to the study of the excitement and spread of acoustic and plasma waves in piezo -apo -beating crystals. One of these achievements is the development of a series of methods for creating effective electro -acoustic converters that can provide the generation and indication of ultrasound in crystals, with quite high operating frequencies and a wide frequency strip.

As a result of studies of the diffusion of a number of impurities in the crystals of cadmium sulfide, it was possible to create converters unique in their characteristics. Bogdanov in the Laboratory of Physics of the semiconductors Fian from G. Sergey Vasilievich was one of the founding fathers and pillars of the institute. His erudition, thoroughness, devotion, fundamentalness and goodwill made a significant contribution to the creation of the atmosphere, which largely contributed to the successful activity of the institute.

” Aleksandrov on the left, on the right - I. Author photo: Viktor Yakovlev Scientific School, thanks to Sergey Vasilievich Bogdanov, a strong scientific school in acoustoelectronics and acousteoptics arose in Siberia: its students and followers work in universities and the Research Institute of the Siberian region. Bogdanov and the Awards of the Russian Federation on acoustoelectronics.

The creation of a scientific school would be impossible without the teaching talent of Sergei Vasilievich, he read several courses for students of Novosibirsk State University, and he led the work of graduate students. It was a weekly uninstall seminar. His face was serious and even, as it seemed to me then, harsh. When it came to questions to the speaker, S. This Bogdanov series did not promise the speaker.

Surroundingly S. The questions were very different: from the formal trifles such as jargon inscriptions on slides, unreasonable terms, and so on, to deep details of the experiment, the measurement process, and the interpretation of the results. No wonder young researchers frankly afraid of his presence in their reports. ” Ryanov in the background, left.

Bogdanov emphasizes that respect for people, friendliness, and tact were features of his character. By the totality of his personal qualities, there is something to strive for. Was Sergey Vasilievich a strict teacher? I think yes. In his speeches, he could reasonably smash not only a negligent student, but also an opponent. And how else. He did not go to a compromise with conscience, I was a witness.

It is difficult to determine what the success of the researcher depends on the success of the researcher, and any creative person. Perhaps from the attitude to their activities? Bogdanov in the Endropy and Life essay emphasized: “Physics, any science is not an archive of the laws of nature, but a whole work! Without noticing the beauty of the world, not trying to know it, not thinking about how to improve it, without the romance of searches, it is impossible to open something new, it is impossible to be a physicist, in general-a scientist!
