Исследован спиновый транспорт в антиферромагнитных проводниках. Спиновый ток инжектировали из ферромагнитной пленки Co в антиферромагнитный проводник FeMn, после чего было исследовано постоянное напряжение, возникающее в слое Pt в условиях ферромагнитного резонанса при различных углах поворота ориентации постоянного магнитного поля в плоскости пленки. Был рассчитан вклад, вызванный чистым спиновым током (спиновой накачкой), зарегистрированный с помощью обратного ...

Semiconductor lead halide perovskites have attracted significant attention for various applications. Understanding the impact of material composition on optical properties is essential for optimizing device performance. Here, we performed magneto-optical spectroscopy on high-quality bulk CsPbBr3, MAPbBr3, and MAPbI3 single crystals under magnetic fields of up to 30 T. The results revealed distinctive excitonic responses to the magnetic ...

In this article, we propose a new two-dimensional CP3 material with distinguished properties from comprehensive first-principles calculations. It has excellent thermal, mechanical, and dynamical stabilities and promise for experimental fabrication. The low cleavage energy (0.57J/m2) implies the plausibility of CP3 single-layer exfoliation from bulk structure. Other than exfoliation, we predict an alternative route to synthesize CP3 monolayer through C atoms doping ...

Two-dimensional (2D) van der Waals heterostructures formed by stacking two different 2D materials have gained immense attention as they have the potential to show interesting properties. Herein, we report the detailed electronic structure of recently synthesized MoS2/SnS2 and MoSe2/SnS2 heterostructures obtained through density functional calculations. Our study shows that the MoS2/SnS2 heterostructure has a type-I band alignment with ...

Cu2ZnGeS4xSe4(1−x) (CZGSSe) single crystals were grown by chemical
vapor transport (CVT) from synthesized polycrystals using iodine as a transport
agent. The elemental analysis showed good agreement with stoichiometry. The values
of the band gap of solid solutions are determined from the transmission spectra in the
region of the absorption edge, and its concentration dependence, which has a
nonlinear quadratic dependence ...

The oxidation of tetraselenatetracene (TSeT) by tetracyanoquinodimethane in the presence of dysprosium(III) tris(hexafluoroacetylacetonate), DyIII(hfac)3, produces black crystals of {TSeT1.5}●+[DyIII(hfac)4]− (1) salt, which combines conducting and magnetic sublattices. It contains one-dimensional stacks composed of partially oxidized TSeT molecules (formal averaged charge is +2/3). Dimers and monomers can be outlined within these stacks with charge and spin ...

The results of the study of the optical properties of low-density InGaPAs quantum dots, as well as the effect of low temperatures and thermal annealing parameters on their optical and structural properties were presented. InGaPAs quantum dots were formed by substituting phosphorus with arsenic in InGaP layer directly during epitaxial growth. The optical properties of ...

Proximity effects in structures with helimagnetic ordering are investigated. Structures with sharp boundaries
were prepared by magnetron sputtering. Results indicating a change in the magnetic state of a helimagnet under
the influence of superconductivity were obtained by polarized neutron reflectometry. A new type of structure with
alternating layers of a superconductor and a rare-earth helimagnet is proposed for ...

The peculiarities of two-state lasing in a racetrack microlaser
with an InAs/GaAs quantum dot active region are
investigated by measuring the electroluminescence spectra
at various injection currents and temperatures. Unlike
edge-emitting and microdisk lasers, where two-state lasing
involves the ground and first excited-state optical transitions
of quantum dots, in racetrack microlasers, we observe lasing
through the ground and second excited states. As ...

In this paper, we demonstrate for the first time an experimental observation of ferromagnetic ordering at temperatures below 60 K in SrIrO3 film which was the upper layer in SrIrO3/La0.7Sr0.3MnO3 bilayers. Epitaxial bilayers were deposited on (1 1 0) NdGaO3 substrates, after which the temperature dependences of the electron spin resonance spectra of the fabricated ...

This paper demonstrates an elastic (i.e., both flexible and stretchable) pixel matrix based on the patterned films of single-walled carbon nanotubes, which were obtained using optical lithography and plasma etching. The proposed elastic electrodes maintain their initial resistivity at 10% stretching. We also demonstrate an application of the elastic pixel matrix to an array of ...

Antibunching effect is typically observed in individual systems possessing photoluminescence (PL) blinking and vice versa. Contrary to this common perception, absence of antibunching in strongly blinking methyl ammonium led tri-iodide (MAPbl3) perovskite crystals of sizes from tens to hundreds of nanometers regardless of the excitation power density is observed. Antibunching effect does not appear even ...

Новые технологии, в том числе технологии Индустрии 4.0, кардинально меняют традиционные и высокотехнологичные отрасли, формируют внутри промышленного комплекса сектор передо- вых производств (ПП). Россия до сих пор характеризовалась скромным присутствием на мировых рынках ПП — менее 0,6% по отдельным рынкам и не более 0,4% по совокупности. Отчасти это связано, в целом, со скудностью товарного разнообразия ...

We demonstrate that the temperature and doping dependencies of the photoluminescence (PL) spectra of a doped MoS2 monolayer have several peculiar characteristics defined by the trion radiative decay. While only zero-momentum exciton states are coupled to light, radiative recombination of non-zero momentum trions is also allowed. This leads to an asymmetric broadening of the trion spectral ...
