- We have theoretically substantiated and experimentally proven new families of non-magnetic topological insulators, both binary and multicomponent. Have studied their electronic and oscillation characteristics.
- The Laboratory has predicted and research new materials showing giant spin orbit splitting of electron states both in the volume and on the surface and on the interface formed by two materials.
- Our researchers have found topological surface states in local crevices of topological insulators in the unoccupied region of energies.
- We have predicted and produced 3D antiferromagnetic topological insulators. We have theoretically and experimentally studied their volume and surface electron structure.
- We have proven that doping only the surface block of non-magnetic topological materials with magnetic admixtures allows to produce systems with quantum abnormal Hall effect.
- Our Laboratory has found new families of two-dimensional topological insulators. We have investigated the main factors affecting formation of quantum spin Hall effect in thin films of 3D topological insulators.
- We have proposed and implemented a method of formation of 2D ferromagnetic systems on surfaces of 3D topological insulators.
- Our researchers have created a theory that allows to describe behavior of heterostructures formed by topological insulators and films of ferromagnetic semiconductors. This theory allows to forecast conditions in which formation of quantum abnormal and quantum spin Hall effects in such structures.
- The Laboratory has predicted and studied theoretically and experimentally existence of Dirac plasmons on the surface of topological insulators.
- We have determined the a universal mechanism of formation of crystalline structure when a topological insulator contacts a magnetic semiconductor or trivial semiconductor during growing using molecular beam epitaxy.
Implemented results of research:
- We have created a unique ion-plasma setup named «SPRUT».
- An ion-plasma technology has been created for modifying surfaces of objects having complex shape. The technology is used for modifying surfaces of objects with blind holes and cogwheels, for modifying internal and external surfaces of medical stents that have the form of cancellated cylinders. Processing surfaces of stents made of titanium nickelide involving silicon ions allows for their rapid endothelization of surfaces when implanting stents into organisms, thus reducing duration of interaction between blood and metal.
- Results of in vivo research in model organisms (minipigs) have show that modifying surfaces of stents allows allows for 1.3-1.5 times shorter time of endothelization. This new technology is unique..
Education and career development:
- We have created and launched the «Non-equilibrium thermodynamics» course for Tomsk State University students majoring in Physics as well as the «Quantum chemistry» for bachelor students of the Faculty of Chemistry.
- 3 doctoral dissertations and 6 candidate dissertations have been defended.
- The Laboratory has organized internships for young scientists younger than 30 at the International Physics Center (Spain) and the Max Planck Institute of Microstructure Physics (Germany). Every year about 10 employees of the Laboratory complete scientific work at the International Physics Center (Spain).
- We have developed a program for career enhancement «Physical and chemical methods of production and study of nano-dimensional, nano-structural materials, coatings and thin films» (72 hours). 67 young researchers have completed internships at the Laboratory within this course.
- The Laboratory has developed a master's program «Quantum theory of condensed-state volume and nano-dimensional systems» for students majoring in Physics (the program is lead by professor Ye. V. Chulkov-Savkin).
- Employees of the Laboratory actively participated in the annual Russian Scientific Student Conference «Solid state physics» in Tomsk, participated in organizing the 24th All-Russian Scientific Conference of Students of Physics and Young Scientists in Tomsk from 31 March to 07 April 2018.
Organizational and structural changes:
In 2001 the Tomsk Materials Science Collective Utilization Center was opened at the Tomsk State University. All the unique equipment purchased within the mega-grant is a part of the Center and is available for Russian employees and is used in the educational process.
