Study of the nature of chemical bonds in the studied materials for controlled influence (by doping, intercalation, deviations from stoichiometry and application of external fields) on the functional characteristics of the studied compounds, specifics of structural phase transitions and rearrangement of electronic states in transitions from semiconductor to metallic state. popup.description2 Theoretical and experimental studies of phosphorus-containing chalcogenide single crystals MM'P2X6 (M, M' - Ag, Cu, In; X - S, Se), which are in phases with spontaneous dipole-spin polarisation and have transitions from the semiconducting to the metallic state, have been carried out. The manifestations of electron-electron and electron-phonon interactions, size effects in van der Waals nanolayer crystals and heterostructures were investigated, their electronic and phonon spectra, ferroelectric, semiconductor and thermodynamic properties were studied; the regularities of dipole and spin ordering were established. The phase diagrams of MM'P2X6 ferroics were constructed depending on the chemical composition and the influence of external fields. The functional parameters of the heterostructures suitable for the development of new bistable or multistable functional electronics elements were determined.  Product Description popup.authors YEVYCH Ruslan M.
