The system of budgetary federalism in the Russian Federation substitutes a complex mechanism for the allocation of fiancial resources between diffrent levels of government, which plays a key role in ensuring the socioe-conomic development of the country. In the context of the rapidly changing situation in the global economy, the system of fical federalism is ...

Comprehensive studies of the luminescence of p–i–n structures with 10 compensated GaAs/AlGaAs quantum wells have been performed. The studies were carried out in the terahertz (THz) and near-infrared (NIR) spectral ranges with both optical and electrical pumping of nonequilibrium charge carriers. The THz photoluminescence spectra revealed an emission line caused by electron transitions from the first size-quantization ...

The interaction of a single-cycle terahertz electric field with the topological insulator MnBi2Te4 triggers strongly anharmonic lattice dynamics, promoting fully coherent energy transfer between the otherwise noninteracting Raman-active Eg and infrared (IR)-active Eu phononic modes. Two-dimensional terahertz spectroscopy combined with modeling based on the classical equations of motion and symmetry analysis reveals the multistage process underlying the excitation of the ...

Terahertz (THz) luminescence in doped nanostructures with GaAs/AlGaAs quantum wells is studied under conditions of interband optical pumping. The study is carried out on compensated quantum wells with different doping profiles. In one structure, compensation is carried out directly in each quantum well by introducing donors and acceptors with the same concentration. In the other, ...

The terahertz radiation in GaAs/AlGaAs quantum wells with different types of doping was experimentally studied under interband optical excitation of nonequilibrium charge carriers. The structures doped only with donors, and the structures with a high degree of compensation of donors by acceptors were studied. The spectra of terahertz radiation associated with charge carrier transitions with ...

Plasmonic interferometry is a rapidly growing area of research with a huge potential for applications in the terahertz frequency range. In this Letter, we explore a plasmonic interferometer based on graphene field effect transistor connected to specially designed antennas. As a key result, we observe helicity- and phase-sensitive conversion of circularly polarized radiation into dc ...

As part of Russia’s transformation process of the last decade, the preconditions for the emergence of philanthropic institutions were created. A plethora of evidence illustrates how this process has unfolded. However, there is a limited amount of research devoted to the philanthropic activity of Russians. This deficit stems from a lack of empirical data on ...
