Nanoscale semiconductor and dielectric films and magnetic nanocrystals – new directions of development of the scientific school of Ya. A. Ugai “Solid state chemistry and semiconductors”. Review

New directions of development the scientific school Yakov Aleksandrovich Ugai “Solid state chemistry and semiconductors” were considered for direction “Study semiconductors nanostructured functional films based on them”, supervised by I. Ya. Mittova. The study students followers A. cover materials science topics in field solid-state inorganic physical chemistry. At present stage research, emphasis is being placed precisely nanoscale objects, since these objects main mechanisms modern are most clearly revealed: methods synthesis - composition structure (degree dispersion) properties. Under guidance Professor Mittova DSc (Chem.), research two key areas conducted:“Nanoscale semiconductor dielectric films” “Doped undoped nanocrystalline ferrites”. In first area, problem creating high-quality AIIIBV effect reasonably selected chemostimulators process thermal oxidation and/or directed modification properties films. They specific results achieved to date, reflecting positive modifiers rate formation thickness range their characteristics, which promising practical applications.Nanomaterials yttrium lanthanum orthoferrites with a perovskite have unique magnetic, optical, catalytic use various approaches doping allowing control wide range. magnetic nanocrystals under supervision Prof. studies impurity composition, structure, nanoparticles replacing Y(La)3+ Fe3+ cations carried out. Socialist Republic Vietnam one talented Mittova, Nguyen Anh Tien, performs this area. To new ofnanocrystals doped ferrites, including ferrites neodymium, praseodymium, holmium, etc. been developed.
