Information × Registration Number 0123U101038, ( 0225U005149  ) R & D request Title Electronic structure, optical and luminescence properties of complex halides, chalcogenides and oxides based on heavy and rare earth metals Head Oleg Y. Khyzhun, д.ф.-м.н. Registration Date 13-02-2023 Organization Frantsevich Institute for Problems of Materials Science National Academy of Science of Ukraine popup.description1 The aim of the work is to study the total and partial densities of electronic states in the valence band and conduction band of complex halides, chalcogenides and oxides based on heavy and rare earth metals on the base of the data of theoretical "first-principle" calculations, as well as performing calculations of the main optical constants, in particular, the optical absorption coefficient α(ω), real ε1(ω) and imaginary ε2(ω) parts of the dielectric function, refractive index n(ω), extinction coefficients k(ω) and optical reflection R(ω), spectrum of electron energy losses L(ω). popup.nrat_date 2024-12-09 Close
