Heterostructures based on ZnO nanorods and CsPbBr3 nanocrystals were investigated for their potential as semiconductor SERS substrates. We found that ZnO morphology governs the efficiency of interfacial energy transfer, leading to enhanced photoluminescence under 390 nm excitation and a noticeable reduction of the bandgap in the composites. Raman analysis revealed a pronounced intensity enhancement and ...

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 ...

We use a subsample of co-detections of the ACT and MaDCoWS cluster catalogs to verify the predicted relation between the observed X-ray flux FX in the 0.5−2 keV band and the cluster mass M500c for halos at z > 0.6 − 0.7. We modified this relation by introducing a correction coefficient, η, which is supposed to encapsulate factors associated with a particular method of flux ...

The reaction of manganese(II) chloride with the azomethine ligand 4-((1H-pyrrol-2-yl)methylene-amino)-4H-1,2,4-triazole (HPyrtrz) affords crystals of 1D polymeric compound [MnII(HPyrtrz)(H2 O)Cl2]n (I). The addition of the coligand 1,10-phenanthroline (Phen) to the synthesis of compound I results in the sequential crystallization of two products: 1D polymeric compound [MnII(Phen)Cl2]n (II) and mononuclear complex [MnII(Phen)2Cl2]·HPyrtrz (III). Complex III is isolated ...

In this study, an off-stoichiometric boron-doped chemically complex intermetallic alloy with a dual phase ordered-L12/disordered-FCC structure was developed, which exhibited an outstanding combination of high strength and ductility. The superior mechanical properties were attributed to the synergistic features of dual-phase microstructure, increased antiphase boundary energy due to the multi-additions of Ti, Nb and Ta elements ...

Добавление нескольких процентов азота в GaP или GaPAs позволяют получить твердые растворы GaPNAs, согласованные по параметру кристаллической решетки с кремниевой подложкой в большом диапазоне значений ширины запрещенной зоны, что дает возможность получения оптоэлектронных кремниевых интегральных схем. Однако материалы с небольшой долей азота являются мало изученными из-за сложности в эпитаксиальном выращивании четверных твердых растворов с тремя ...

The changes in the substituted La0.5Sr0.5FeO3−γ orthoferrite under vacuum annealing in the temperature range of 200–650 °C have been studied by X-ray diffraction analysis, as well as Mössbauer and Raman spectroscopy. Annealing of the as–prepared ferrite with the rhombohedral structure (R 3‾ c) resulted in its transition to the cubic one (Pm 3‾ m) at 650 °C. In the as–prepared ferrite being paramagnetic ...
