Influence of strong electron correlations on the form of the x-ray Cu K absorption spectra of La2-xSrxCuO4 / P. V. Avramov, S. G. Ovchinnikov // J. Exp. Theor. Phys. - 2011. - Vol. 81, Is. 4. - P. 811-816. - Cited References: 24. - We thank the Scientific Council for the Problem of HighTemperature Superconductivity for support under Project . - ISSN 1063-7761
Аннотация: The influence of strong electron correlations on the x-ray Cu K absorption spectra has been investigated using the extended p-d model and the sudden approximation. The structure of the vacant above-threshold single-electron Cu p states has been modeled by the SCF X, scattered wave method. It has been shown that the Cu K spectrum is determined by a convolution of the spectra of single-electron absorption by vacant orbitals below and above the ionization threshold and of many-electron transitions within the system of valence electrons. This makes it possible to attribute the main peak of the Cu K spectrum of La2Cu04 to the Cu dlOL configuration and the single high-energy satellite to the Cu d9 configuration. The LaSrCu04 spectrum has been calculated with allowance for both singlet and triplet two-hole states of the CuO, cell. Comparison with experimental data reveals that the main two-hole state is a triplet, which also forms the absorption spectrum consisting of the main maximum corresponding to the Cu ~'OLL configuration and two satellites corresponding to the Cu d9L and Cu d8 configurations. All the theoretical spectra obtained agree well with the experimental data. O 1995 American Institute of Physics.

Аннотация: Проведено теоретическое исследование электронного строения комплексов фуллерена C[60] с двумя атомами лития и азотдопированных фуллеренов с целью их последующего сравнения и изучения изомерного эффекта для данных соединений. В структуре электронных уровней этих соединений имеется внедренное состояние, расположенное в запрещенной зоне, появление которого обусловлено наличием в молекулах дополнительной пары электронов. Однако комплексы с литием имеют еще одно отличие - существенное расщепление уровней вследствие влияния положительно заряженных атомов лития. Ширина запрещенной щели и средняя энергия связи в комплексе фуллерена с литием зависят как от характера многоугольника, возле которого они координированы, так и от расстояния между интеркалированными атомами. В азотдопированных соединениях также наблюдается подобная зависимость, однако она носит неупорядоченный характер

Аннотация: The structure of the interfaces and the mechanisms of induced spin polarization of 1D infinite and finite narrow graphene- and h-BN zigzag nanoribbons placed on a SrO-terminated La1-xSrxMnO3 (LSMO) (001) surface were studied using density functional theory (DFT) electronic structure calculations. It was found that the pi-conjugated nanofragments are bonded to the LSMO(001) surface by weak disperse interactions. The types of coordination of the fragments, the strength of bonding, and the rate of spin polarization depend upon the nature of the fragments. Infinite and finite graphene narrow zigzag nanoribbons are characterized by the lift of the spin degeneracy and strong spin polarization caused by interface-induced structural asymmetry and oxygen-mediated indirect exchange interactions with Mn ions of LSMO support. Spin polarization changes the semiconducting nature of infinite graphene nanoribbons to half-metallic state with visible spin-up density of states at the Fermi level. The h-BN nanoribbon binding energy is weaker than graphene nanoribbon ones with noticeably shorter interlayer distance. The asymmetry effect and indirect exchange interactions cause spin polarization of h-BN nanoribbon as well with formation of embedded states inside the band gap. The results show a possibility to use one-atom thick nanofragments to design LSMO-based heterostructures for spintronic nanodevices with h-BN as an inert spacer to develop different potential barriers.

Graphene nanoribbons -- DFT -- LSMO thin films -- Induced spin polarization -- h-BN nanoribbons -- Half-metal
Аннотация: Induced spin polarization of π-conjugated carbon and h-BN low dimensional fragments at the interfaces formed by deposition of pentacene molecule and narrow zigzag graphene and h-BN nanoribbons on MnO2-terminated LSMO(001) thin film was studied using GGA PBE+U PAW D3-corrected approach. Induced spin polarization of π-conjugated low-dimensional fragments is caused by direct exchange with Mn ions of LSMO(001) MnO-derived surface. Due to direct exchange, the pentacene molecule changes its diamagnetic narrow-band gap semiconducting nature to the ferromagnetic semiconducting state with 0.15 eV energy shift between spin-up and spin-down valence bands and total magnetic moment of 0.11 μB. Direct exchange converts graphene nanoribbon to 100% spin-polarized half-metal with large amplitude of spin-up electronic density at the Fermi level. The direct exchange narrows the h-BN nanoribbon band gap from 4.04 to 1.72 eV in spin-up channel and converts the h-BN ribbon semiconducting diamagnetic nature to a semiconducting magnetic one. The electronic structure calculations demonstrate a possibility to control the spin properties of low-dimensional π-conjugated carbon and h-BN fragments by direct exchange with MnO-derived LSMO(001) surface for spin-related applications.

Transition metal dihalides -- Monolayers -- DFT -- Hubbard correction -- Band structure
Аннотация: Electronic structure and magnetic properties of the family of first-row transition metal dihalides (TMHal2, TM = V, Cr, Mn, Fe, Co, Ni; H = Br, I) monolayers were studied by means of density functional theory. Strong electron correlations were taken into account by implementing Hubbard U correction in a simplified scheme proposed by Dudarev et al. (Ueff). Ueff correction essentially affects electronic structure of TMHal2 widening the band gap and witnessing their highly spin-polarized nature. Two different ligand orientations namely, H and T configurations of monolayers were considered. Unlike others, FeHal2 monolayers tend to form H structure when Ueff correction is included. © 2019 Elsevier Ltd

Impact diamonds -- lonsdaleite -- compressibility -- high-pressure -- diamond/lonsdailete biphases
Аннотация: For the first time, lonsdaleite-rich impact diamonds from one of the largest Popigai impact crater (Northern Siberia) with a high concentration of structural defects are investigated under hydrostatic compression up to 25 GPa. It is found that, depending on the nature of a sample, the bulk modulus for lonsdaleite experimentally obtained by X-ray diffraction in diamond-anvil cells is systematically lower and equal to 93.3–100.5% of the average values of the bulk moduli of a diamond matrix. Density functional theory calculations reveal possible coexistence of a number of diamond/lonsdaleite and twin diamond biphases. Among the different mutual configurations, separate inclusions of one lonsdaleite (001) plane per four diamond (111) demonstrate the lowest energy per carbon atom, suggesting a favorable formation of single-layer lonsdaleite (001) fragments inserted in the diamond matrix. Calculated formation energies and experimental diamond (311) and lonsdaleite (331) powder X-ray diffraction patterns indicate that all biphases could be formed under high-temperature, high-pressure conditions. Following the equation of states, the bulk modulus of the diamond (111)/lonsdaleite (001) biphase is the largest one among all bulk moduli, including pristine diamond and lonsdaleite.

Suzuki cross-coupling -- Yamamoto polycondensation -- Density functional theory
Аннотация: Using Suzuki and Yamamoto coupling reactions, copoly-(9,9-dioctylfluorenes) (CPF) were synthesized and compared regarding their photophysical properties using the spectroscopic and ab initio DFT approaches. The CPFs were functionalized by benzo [2,3,5] thiadiazole (BT) or carbazole-3,6-diyl (3,6-Cz). The latter was used to introduce different luminophore fragments, including Nile red and 4-pyrrolidinyl-1,8-naphthalimide derivatives. The effect of the two synthesis techniques on the polymer microstructure, the influence of embedding of 3,6-Cz moieties in the polymer backbone on polymer structuring, and the impact of the end groups like novel quinoxaline-containing compounds on the luminescent properties of CPFs were investigated. By comparing electron density distribution using the ab initio DFT approach with photoluminescence, it was shown that Suzuki reaction provides a chain microstructure with individual BT fragments separated by 9,9-dioctylfluorene monomeric units, while Yamamoto reaction leads to the blocks of BT units. This effect leads to different CPF photophysical properties (absorption and emission spectra).

Аннотация: Предложена новая схема образования фуллеренов, основанная на анализе сходства между экспериментально зафиксированными углеродными структурами. Первоначально, согласно эксперим. данным, идет синтез микрокластеров C[2] и C[10], затем из них собирается либо промежуточный кластер-зародыш, либо готовый низший фуллерен. Из кластер-зародыша с "хорошей" симметрией может с достаточно высокой вероятностью собираться фуллерен высокой симметрии. Рассмотрены атомные и электронные структуры таких молекул, как C[36], C[60], C[70], C[76],... ; для C[36] рассчитаны ЯМР спектры и сопоставлены с эксперим. данными
