One of our main aims is the study of many-particle (cooperative) effects in kinetics of bimolecular reactions in condensed matter, including radiation defects. Most of this research is based on a novel formalism of many-particle densities described in our book [E.A. Kotomin and V.N. Kuzovkov, "Modern aspects of diffusion-controlled reactions" (Amsterdam: Elsevier, 1996)].
Surface-induced reactions are known to play a very important role in heterogeneous catalysis. We study these reactions with emphasis on such fundamental phenomena as pattern formation, reactant self-organisation, regular and irregular reactant concentration oscillations as well as chaotical behavour in the case of simple reactions on low-index crystalline surfaces. Another two activities deal with the growth mode of thin metallic films on oxides and diffusion in ceramics, composites and heterogeneous media which is of great importance for the interpretation of experimental data.
We use methods of parallel computer simulations in first-principles (ab initio), molecular dynamics, as well as empirical, shell modelling of numerous prospective technological materials used, e.g. in cathodes of solid oxide fuel cells and lithium batteries. For advanced perovskites and ferroelectrics, we mainly simulate defect-induced and surface-induced processes.
In our theoretical studies (closely cooperated with experimental groups) we combine fundamental research (the Anderson localization) with very applied and technologically important problems (new nanomaterials).
Scheme of the multiscale simulation of CNT-interconnected IC backend structure
We combine several different techniques, including analytical formalisms and large-scale computer simulations (quantum chemical methods, molecular dynamics, stochastic simulations as well as Monte Carlo/cellular automata modeling). See more Equipment and Latvian Super Cluster Homepage
