Study of charge carrier transport processes in electric and magnetic fields in low-dimensional transition metal dichalcogenides (LDM-DPM), oxide ferroics (ABO3) and in polymer composites based on them and determination of the main factors that influence these processes. The research covers molybdenum and tungsten disulfides in the form of 2d-powders and/or nanoflake arrays and oxide ferroic powders, primarily such as: BaTiO3, SmxBi1-xFeO3-z, HfxZr1-xO2. It is proposed to investigate the influence on the processes of current carrier transport of such factors as: structural polytype of LDM-DPM, structural defects that arise during the manufacturing process of materials (intrinsic defects) and during temperature annealing in an atmosphere of various gases, under the influence of plasma treatment and high-energy electron irradiation, compression deformation. It is planned to study the type and energy structure of defects, the mechanisms of their thermal annealing, and to determine the radiation stability of the studied materials. Studies conducted on samples with a certain type of structural polytype of HP-DPM will also allow obtaining information about possible changes in the polytype under the influence of the above factors. The applied goal of the project is to develop recommendations for the targeted change and optimization of the electronic transport properties of low-dimensional transition metal dichalcogenides and oxide ferroins by modifying the structural state for new applications in nanoelectronics and sensors.
