Демонстрируется влияние длины края двумерного топологического изолятора на основе квантовой 8 нм ямы HgTe на нелокальный транспорт. Предложена и реализована геометрия структуры типа длинного края. Показано, что вклад длинного края в кондактанс мал по сравнению с вкладом короткого края. Данная геометрия позволяет полностью поляризовать ток по спину. ...

В работе рассмотрены основные варианты детектирования водорода, а также приведены требования, которые предъявляются к сенсорам водорода. Проанализированы преимущества и недостатки существующих решений по детектированию водорода и проведен сравнительный анализ основных метрик коммерчески доступных сенсоров водорода. Было установлено, что оптические сенсоры преодолевают основную проблему существующих сенсоров – использование электрического тока в чувствительной зоне сенсоров. Данная обзорная ...

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 ...

The stability of the dumbbell structure has been confirmed by previous theory and experiment. Based on first-principles calculations, we proposed hexagonal dumbbell graphene (HDB C10) and rectangular dumbbell graphene (RDB C10) monolayers containing periodically raised C (CR) atoms. They turn out to have high mobility semiconductor properties. By adsorbing H atoms on these CR atoms, ...

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 ...

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 ...

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 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 ...

The influence of individual impurities of Fe on the electronic properties of topological insulator Bi2Se3 is studied by Scanning Tunneling Microscopy. The microscope tip is used in order to remotely charge/discharge Fe impurities. The charging process is shown to depend on the impurity location in the crystallographic unit cell, on the presence of other Fe impurities ...
