context_page_description: Igor Serafimovich Tashlykov was a USSR and Belarusian physicist, Doctor of Science, Professor, member of the New York Academy of Sciences, and Belarusian Physical Society. Places of work, positions: Research Institute of Applied Physical Problems of Belarusian State University, Belarusian State Technological University, Maxim Tank Belarusian State Pedagogical University.
  I.S. Tashlykov was a well-known scientist in Belarus, Russia and abroad in the field of surface modification of solids using ion-beam technologies. He made a significant contribution to the development of solid-state electronics by developing criteria for controlling the transformation of the structure of ion-implanted gallium arsenide, silicon, based on the calculations of the energy density released in the elastic processes of cascade collisions of atomic nuclei. Tashlykov also developed methods for the modification of solids by atomic mixing and ion-assisted deposition of coatings. Experimental studies are generalized in the developed by him theory of ion-assisted deposition of thin films.
context_section_description: As a scientist, I.S. Tashlykov grew up in the A.N. Sevchenko Scientific Research Institute of APP of BSU. Carrying out the study of radiation disturbances in bismuth and its alloys by nuclear physical methods, Tashlykov initiated the creation of a research complex of nuclear physical methods on the basis of the ESU-2 electrostatic accelerator of horizontal type in the Belarusian State University in 1975-1979. This legendary accelerator number 2, built shortly after the Great Patriotic war in the laboratories of Kharkov Institute of Physics and Technology, was used in the 60s and 70s as an electron accelerator at PIAS in the sector of Professor V.S. Vavilov. With the assistance of the director of the Research Institute of the APP, Academician of the Academy of Sciences of Belarus, A.N. Sevchenko, head of the semiconductor laboratory Academician B.M. Vul passed this accelerator to Belarus.
  Organization of a new research center based on ESU-2,  the reconstruction of the accelerator (the creation of a high-frequency ion source and its control systems), the logistic support (transmission of a target chamber equipped with a two-axis precision goniometer) of the elionics laboratory was greatly assisted by well-known specialists: L.I. Pivovar (KPTI), G.M. Osetinsky and I.A. Chepurchenko from the Joint Institute for Nuclear Research (Dubna), as well as Tashlykov's colleague and friend Dr. Hardwig Treff of the University of Jena (Friedrich Schiller Jena University, Jena, GDR).
  From the beginning of the 70s research work began in the BSU under the guidance of Associate Professor G.A. Gumansky on the tasks of the State Committee on Science and Technology of the Council of Ministers of the USSR in a new direction associated with ion-beam synthesis of double and triple connections of optoelectronics materials. The importance and relevance of the research in this direction has led to active international cooperation. In 1971-1972, 1973, 1975, 1977 Tashlykov repeatedly carried out research at the University of Jena (Friedrich Schiller Jena University, Jena, GDR), at the invitation of the heads of the ionometric department Gustav Schirmer and Gerhard Goetz.
  In 1977, at the International Conference on Atomic Collisions in Solids (ICACS) at the Moscow State University, organized by Professor A.F. Tulin, Tashlykov became acquainted with Professor John A. Davies from the Chalk River Nuclear Laboratories, known as one of the fathers of ion implantation, and Professor George Carter of Salford University (Salford University, Manchester, UK), a famous theoretician in the field of ion implantation.
  At the invitation of Professor John A. Davis in 1979-1980 Tashlykov underwent traineeship at the McMaster University (McMaster University, Hamilton, Canada) and in the Chalk River Nuclear Laboratories in Canada. Defect formation in gallium arsenide was studied during implantation of N, Al, P, As, and Sb ions under conditions of controlled energy density released in cascades of atomic collisions at temperatures from 40 K to several hundred degrees Celsius with ion current density from hundredths to units of μA / cm². Using the Rutherford backscattering (RBS), the distribution profiles of the implanted As, Sb were established using the ²⁷Al (p,γ)²⁸Si resonance nuclear reaction of aluminum profiles in gallium arsenide. These results, as well as the results of studies of the modification of the catalytic properties of nickel electrodes for water alkaline electrolysis for the production of hydrogen, formed the basis for a doctoral dissertation. New knowledge was obtained about the mechanisms of formation of radiation damage and phase reconstruction of the structure in gallium arsenide under ion irradiation, the influence of ion current density on these processes, the energy density released in the cascade of atomic collisions, the type of ions, and the irradiation temperature.
  The results of the studies in Canada of ion implantation into electrodes used in alkali electrolysis for the production of hydrogen and oxygen were reported by Tashlykov at the Instit
