We perform a magneto-optical study of a two-dimensional electron systems in the regime of the Stoner
ferromagnetic instability for even quantum Hall filling factors on MgxZn1−xO/ZnO heterostructures. Under
conditions of Landau-level crossing, caused by enhanced spin susceptibility in combination with the tilting of the
magnetic field, the transition between two rivaling phases, paramagnetic and ferromagnetic, is traced in ...

Представлены результаты теоретических и экспериментальных исследований экситонных эффектов в мономолекулярных слоях дихалькогенидов переходных металлов. В этих двумерных полупроводниках прямая запрещённая зона шириной порядка 2 эВ реализуется на границах зоны Бриллюэна, а энергия связи нейтральных и заряженных экситонов составляет сотни и десятки миллиэлектронвольт соответственно. Таким образом, оптические свойства монослоёв дихалькогенидов переходных металлов контролируются электронно-дырочными кулоновскими комплексами. Обсуждаются ...

Manifestations of quantum interference effects in macroscopic objects are rare. Weak localization is one
of the few examples of such effects showing up in the electron transport through solid state. Here, we show
that weak localization becomes prominent also in optical spectroscopy via detection of the electron spin
dynamics. In particular, we find that weak localization controls the ...

The influence of light illumination of ohmic contacts to high-ohmic gallium arsenide and cadmium telluride samples is investigated. It is revealed, that near-contact –area illumination influences not only upon transition resistance, but also upon volume conductivity of the samples due to increasing of free carrier concentration. The new method of separate determination of ohmic contact ...

We have focused on the ability to tune the aluminum (Al) content of the AlGaAs alloy along the growth direction in inverted pyramids (by MOVPE), thus tailoring the potential along a QWR nanostructure. Three parabolic-potential QDs (PQDs) of different potential gradients have thus been realized. The parabolic profiles were changed systematically by fixing the minimum ...

We demonstrate that non-equilibrium spin excitations drift to macroscopically large distances in a 2D electron gas (symmetrically doped GaAs/AlGaAs quantum well) in a quantizing magnetic field at filling factor $\nu $ = 2. The effect is induced by low-temperature photoexcitation of a dense ensemble of long-lived ($\sim 1 $ ms) spin excitations − cyclotron spin-flip magnetoexcitons. The spin excitation ...

Optical spectra of two-dimensional transition-metal dichalcogenides (TMDC) are influenced by complex multiparticle excitonic states. Their theoretical analysis requires solving the many-body problem, which in most cases, is prohibitively complicated. In this work, we calculate the optical spectra by exact diagonalization of the three-particle Hamiltonian within the Tamm-Dancoff approximation where the doping effects are accounted for ...

We report the study of transport and magnetic properties of the YbB6–δ single crystals grown by inductive zone melting. A strong disparity in the low temperature resistivity, Seebeck and Hall coefficients is established for the samples with the different level of boron deficiency. The effective parameters of the charge transport in YbB6–δ are shown to ...

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 ...
