Information × Registration Number 0204U003577, 0101U004538 , R & D reports Title Fundamental characteristics of the new materials with the layered structure including optaned by an intercalation method. popup.stage_title Head Bercha D., Registration Date 26-03-2004 Organization Uzhgorod National University popup.description2 The ab initio investigations of the band structures (with and without taking into consideration the spin polarization) and the electron density distribution for the YAlO , TI AsS , CdSb, FeGa S , NiGa S , Fe P S , CuCrP S crystals with the full symmetry description within the framework of the minimal band complexes concept and Zak"s band representations have been carried out. The localized and delocalized states of the layered crystals intercalated by the magnetic impurities, forming the covalent bridges due to s-d intercation, have been investigated. Within the framework of new approaches to the envelope function method (Karavaev-Tikhodeev-Foreman concept) the energy states in the heterostructures based on GaAs/AlAs as model material using the symmetry of the problem have been investigated. Also the ab initio calculations of the energy spectra of the superlattices have been carried out, including superlattices with the magnetic layers.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
