Young FLNR researcher won the Presidential RSF Grant Competition

Grants, 12 July 2020

On 3 July, the Russian Science Foundation announced the winners of the competitions for early-career researcher 2020 of the Presidential programme for research projects. One of the winners in the competition for the support of initiative research by young scientists was Ruslan Rymzhanov, Candidate of Physics and Mathematics, a researcher of the Flerov Laboratory of Nuclear Reactions JINR.

The project by Ruslan Rymzhanov has received two-year support from the RSF and is called “Modeling of nanostructures formation at the surface of dielectrics irradiated with high-energy heavy ions”.

The aim of the project is the investigation of the fundamental laws of the formation of structural defects on the surface of materials for physical and nanotechnological applications induced by high-energy heavy ions. This work proposes a quantitative study of the processes of the formation of surface defects in dielectric materials for nanotechnological applications (Al2O3, Y3Al5O12, CaF2, MgO, SiO2, LiF), which will allow considering in dynamics the mechanisms of formation of nanostructures on the surface and in the interface regions. The results of such studies can be used to predict nanoscale structural changes and physical properties of composite materials irradiated with heavy ions.

As major results in the implementation of the project, the description of mechanisms of excitation of electronic and ion subsystems and their further relaxation in the near-surface region of various materials was made (Al2O3, Y3Al5O12, CaF2, MgO, SiO2, LiF) in the tracks of fast heavy ions, as well as the dependence was found out of the structural response of these materials on the imposed excitation from the parameters of incident ions and basic properties of solids.
