We present a photoluminescence study of In (As, P) monolithic nanoinclusions into Si (100) substrates. The structures were grown in openings of the silicon substrates using an original approach based on the metal-organic vapor epitaxy method. The obtained arrays of In (As, P) nanoinclusions into the Si (100) surface were investigated by scanning microphotoluminescence spectroscopy. ...

The flow of electric current in quantum well breaks the space inversion symmetry, which leads to the dependence of the radiation transmission on the relative orientation of current and photon wave vector, this phenomenon can be named current drag of photons. We have developed a microscopic theory of such an effect for intersubband transitions in ...

We demonstrate evidence of coherent magnetic flux tunneling through superconducting nanowires patterned in a thin highly disordered NbN film. The phenomenon is revealed as a superposition of flux states in a fully metallic superconducting loop with the nanowire acting as an effective tunnel barrier for the magnetic flux, and reproducibly observed in different wires. The ...

Существование однослойных нанотрубок, не нагруженных внутренним давлением, свидетельствует о необходимости учета моментного взаимодействия между атомами. В противном случае, слой атомов, формирующий нанотрубку, не имел бы изгибной жесткости, а стало быть, однослойная нанотрубка была бы неустойчива.
Ситуация здесь та же, что и в континуальной макромеханике. В основе таких популярных в инженерных расчетах континуальных моделей, как стержни и ...

Atomically thin semiconductors provide an ideal testbed to investigate the physics of Coulomb-bound many-body states. We shed light on the intricate structure of such complexes by studying the magnetic-field-induced splitting of biexcitons in monolayer WS2 using polarization-resolved photoluminescence spectroscopy in out-of-plane magnetic fields up to 30 T. The observed g factor of the biexciton amounts to about −3.9, closely matching the g factor ...

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 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 ...

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 ...

We present thorough measurements of the intrinsic detection efficiency in the wavelength range from 350 to 2500 nm for meander-type TaN and NbN superconducting nanowire single-photon detectors with different widths of the nanowire. The width varied from 70 nm to 130 nm. The open-beam configuration allowed us to accurately normalize measured spectra and to extract ...

A theoretical model is suggested to determine the critical conditions for generation of circular prismatic misfit dislocation loops in hollow core-shell nanoparticles. Based on a strict solution of the linear elasticity boundary-value problem for a circular prismatic dislocation loop in a free-surface shell, we examine the loop formation energy in the nanoparticle and show a ...

Single layer of InAs quantum dots (~ 2.6 ML coverage) in a GaAs well sandwiched by two AlGaAs barriers are incorporated into the tube wall as the gain media.

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.

High-speed photodetectors based on InGaAs/GaAs quantum well–dot nanostructures have been investigated. A bandwidth of 8.2 GHz at a level of ‒3 dB and a wavelength of 905 nm has been demonstrated. It is shown that the speed of internal processes in quantum well–dots make it possible to create photodetectors with a bandwidth of up to ...

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 ...

In this paper, we argue that the electron skew scattering on paramagnetic impurities in non-magnetic systems, such as bulk semiconductors, possesses a remarkable fingerprint, allowing us to differentiate it directly from other microscopic mechanisms of the emergent Hall response. We demonstrate theoretically that the exchange interaction between the impurity magnetic moment and mobile electrons leads ...
