Studies of materials modified by the action of compression plasma flows, high-current election beams, high power ion beams (XRD, SEM, TEM, AFM, AES, RBS, photovoltaic properties, micro-indentation mechanical tests); leader of the research project “Structure-phase transformations in metal-silicon systems under the action of compression plasma flows”; manager of the project “Regularities of structural-phase transformations in silicon and metal-silicon systems under the action of high-intensity electron beams”

Responsibilities: - Teaching Courses: Thin Films Physics, Diffraction Analysis, Nuclear Physics, Technical Diagnostics and Non-Destructive Testing, - Supervision of students’ research

Responsibilities: studies of materials modified by the action of compression plasma flows, high-current election beams, high power ion beams (XRD, SEM, AFM, AES, RBS) Key achievements: - description of structural changes under the action of compression plasma flows (silicon dendrites formation, formation of nanoscaled eutectic alloy in the inderdendritic space); - description of contact melting and diffusion at “metal-silicon” interface under the action of compression plasma flows.

Key achievements: - the effect of surface hardening in metals and alloys by plasma action on “metal-on-metal” systems was achieved; - the effect of deep uniform alloying of materials was achieved by the action of compression plasma flows on “coating-substrate” systems; - the effect of silicide formation (NiSi, NiSi2, FeSi2,CrSi2, TiSi2, Ti5Si3, MoSi2, Mo5Si3, ZrSi2) by the action of compression plasma flows was found for the first time;
