Authors: Asida Andrita
Published: January 2023

Preeclampsia is a specific hypertensive disease in pregnancy with multi-organ involvement. It usually occurs around 20 weeks of gestation and before delivery. The condition of pregnancy with preeclampsia makes the mother more susceptible to experiencing psychological disorders, one of which is depression. Depressive disorders experienced during pregnancy can affect the baby's health condition. Psychological disorders in the form of depression can cause individuals to have a poor quality of life. This study aimed to analyze the relationship between depression and the quality of life of pregnant women with preeclampsia in Lumajang Regency.

Mitos Sobre Bullying
Authors: Fernandes Grazielli , Dalbosco Dell'Aglio Débora
Published: January 2023

Desde o século XIX, o bullying tem sido estudado em todo o mundo e, com o passar do tempo, sua nomenclatura e definições foram sofrendo modificações. Trata-se de um fenômeno social complexo, caracterizado por agressões intencionais e repetitivas, praticadas por uma pessoa ou um grupo contra uma ou mais vítimas sem condições de defesa. Ao mesmo tempo em que a comunidade científica tem se dedicado a estudar o bullying, há, no senso comum, muitos mitos que o minimizam e, por vezes, impedem a adoção de medidas para preveni-los. Assim, este ensaio teórico tem por objetivo analisar mitos em torno do fenômeno bullying, discutindo-os com base em estudos científicos sobre a temática. Reforça-se a necessidade de se implementar programas antibullying em todas as escolas, com investimento e interesse do poder público e da sociedade. Conclui-se que os mitos apenas reforçam estereótipos e impedem a adoção de medidas eficazes de prevenção.
Low frequency Compressional modes in degenerate semiconductor plasmas
Authors: Rozina Ch.  , Maryam N.
Published: January 2023

Properties of low frequency compressional electromagnetic wave pulse in a magnetized semiconductor hole-electron plasma, are investigated. The quantum mechanical effects such as Fermi pressure, quantum tunneling and exchange-correlation potential of inertialess electrons, inertial holes and stationary charged ion particulates are considered in the presence of the magnetic field. A new type of dispersion relation is derived for low-frequency compressional waves by employing quantum magneto-hydrodynamic model and Maxwell equations; the dispersion relation is then analyzed for parallel, perpendicular and oblique propagation of compressional electromagnetic wave pulse to the external magnetic field direction. We have analyzed the obtained dispersion relations numerically, for different semiconductor plasma such as GaAs, GaSb and, GaN, the graphs shows that the frequency of compressional electromagnetic wave pulse decreases with increase of electron-hole density concentration, whereas the frequency increases with the increase of angle of propagation compressional electromagnetic wave pulse. Our results are applicable to understanding the dynamics of semiconductor plasma to produce high power, high band-width devices in contrast to the existing gas plasma devices. Keywords: degenerate semiconductor plasma, quantum mechanical effects, compression electromagnetic wave, gas plasma device.

XXVI International Symposium Nanophysics and Nanoelectronics", Nizhny Novgorod, March 14-March 17, 2022 Effect of chemical passivation of GaAs(001) surface on anisotropy and orientation of gold nanoclusters formed on it and their plasmons
Authors: Berkovits V. L.  , Kosobukin V. A.  , Ulin V. P.  , Alekseev P. A.  , Soldatenkov F. Yu.  , Levitskii  V. S.
Published: January 2023

The principal role of chemical passivation of GaAs surface in the formation on it of oriented anisotropic nanoclusters of gold is discussed. The nanoclusters are fabricated by thermal annealing of a gold film deposited onto GaAs(001) surface passivated as a preliminary by a monolayer of nitrogen or sulfur atoms. These atoms, bonded chemically to gallium atoms of the crystal surface, form a crystal lattice and prevent the chemical interaction of Au with GaAs. As a result of annealing, the arrays of anisotropic (elongated) nanoclusters of chemically pure Au oriented preferably in crystal [110] direction are formed on passivated GaAs(001) surface. The presence of strong anisotropy and orientation of Au clusters on passivated GaAs surfaces is established by the methods of probe diagnostics and of optical reflectance anisotropy spectroscopy and polarized reflection spectroscopy. Using an optical model of plasmonic polarizability of elongated Au spheroids, it is shown that the spectral features observed in polarized reflection originate from anisotropic plasmons of Au nanoclusters polarized mainly in direction [110] of crystal. Keywords: semiconductor surface, nitride passivation, gold nanoclusters, anisotropic plasmons, polarized reflectance.

It was found that at certain cone angles in nanowire there is an extended area of sufficiently high deformations comparable or even large than the deformation at the base of the nanowire. So, for example, when bending the conical (conical coefficient a=-0.7) nanowire with length L=1 μm and radius R=50 nm by Delta z=200 nm, the maximum deformation values are εxx,max=8%, while more than 95% of the nanowire is deformed by >3%. Keywords: nanowires, elastic deformations, conical nanowires, Young's modulus.

We have optimized the growth conditions of the buffer layer for further deposition of Pb1-xSnxTe (x≥0.4), which has the properties of a crystalline topological insulator. To this end, a three-component heterostructure consisting of CaF2, BaF2, and Pb0.7Sn0.3Te : In layers was formed and optimized on the Si(111) surface. The surface morphology of this structure was studied depending on the temperature growth regimes and the optimal combination of growth parameters was selected from the point of view of smoothness and crystalline quality.

The surface density of charge current in two-dimensional double-periodic n-type semiconductor superlattices is calculated in the one-electron approximation in an external magnetic field in the presence of a temperature gradient. The magnetic field was assumed to be constant, uniform, applied perpendicular to the plane of the electron gas. The joint solution of the Schrodinger equation and the kinetic Boltzmann equation is shown that the dependence of the transverse surface density of the current about temperature and module temperature gradient are significantly non-linear in nature, there are areas with negative differential conductivity. The dependence of the relaxation time on the quasi-momentum of the electron is taken into account in the model phenomenologically through the dispersion law of carrier in magnetic subbands. At the lack of inversion symmetry the dispersion laws of magnetic subbands are not even functions of the quasimomentum defined in magnetic Brillouin zone. As a result, the transverse surface thermo-magnetic current increases in many times in comparison with symmetric case Keywords: thermo-magnetic effect, two-dimensional doubly periodic semiconductor superlattices.

Computational and experimental studies of the characteristics of a high-power AlGaAs/InGaAs/GaAs DpHEMT were performed. A self-consistent numerical solution of the Schrodinger and Poisson equations was used to calculate the band diagram and the electron concentration in the channel of the transistor under study. The electron mobility in the transistor channel was estimated experimentally at 9300 cm2/V·s. The obtained transfer current--voltage characteristic of the transistor was used to calculate the parameters of a model differential amplifier (small-signal gain and third-order non-linear distortion factor). Keywords: AlGaAs/InGaAs/GaAs DpHEMT, nonlinear distortion, spacer layers.

Ag8Ge1-xMnxTe6 solid solutions with different manganese content (x=0, 0.05, 0.1, 0.2) were prepared by alloying and further pressing the powders under a pressure of 0.6 GPa. By the X-ray diffraction studies have shown that the introduction of manganese atoms leads to the compressibility of the Ag8GeTe6 lattice. All p-type samples had high resistance below the transition at temperatures of 180-220 K. An increase in electrical conductivity in the range of 220-300 K was analyzed using the Mott ratio; at temperatures T>320 K, semiconductor behavior is observed in all compositions. The highest thermoelectric figure of merit ZT=0.7 at 550 K was obtained for a solid solution of the composition Ag8Ge1-xMnxTe6 (x=0.05).

The electroluminescent characteristics of the InAs/InAs1-ySby/InAsSbP asymmetric light-emitting diode heterostructures with high InSb mole fraction in the active region (y>0.09) in the temperature range 4.2-300 K have been studied. Stimulated emission was achieved in the wavelength range 4.1-4.2 μm at low temperatures (T<30 K). It was found that the electroluminescence spectra were formed as a result of the superposition of contributions from different channels of radiative recombination of charge carriers near the type II heterointerface. The effect of the quality of the type II InAsSb/InAsSbP heterojunction on the radiative interface transitions with an increase in the content of InSb in the ternary solid solution is considered. Keywords: heterojunctions, InAs, antimonides, electroluminescence, light-emitting diodes.

It is shown that the change in the resistivity of crystals of solid solutions (Bi2-xSbx)Te3 (0<x<2) p-type in the temperature range preceding the onset of intrinsic conductivity is due not only to a change in the static relaxation time, the behavior of which in the temperature range from 80 to 300 K is determined mainly by carrier scattering on the vibrations of the crystal lattice, but also by changing the concentration of light holes. The latter is a consequence of the transition of charge carriers from the subzone of heavy holes to the subzone of light holes, as a result of which the concentration of light holes, which make the main contribution to electrical conductivity, decreases with increasing temperature. As a consequence, the plasmon energy proportional to the concentration of charge carriers also decreases with increasing temperature, and the energy of this transition, comparable to the plasmon energy, increases. In this regard, crystals (Bi2-xSbx)Te3 have a specific feature due to the convergence of the plasmon energy and the interband transition, which creates conditions for increasing the intensity of the electron-plasmon interaction. Keywords: thermoelectric materials, bismuth and antimony tellurides, resistivity, interband transitions, plasma of free charge carriers.

A role of subsidiary L- and X-valleys, complex structure of the valence band and orientation dependence of the ionization coefficients are taken into account. A new approach to the choice of semiconductor materials with a large ratio of the ionization coefficients of holes and electrons to create the noiseless avalanche photodiodes due to monopolarity of hot charge carrier multiplication is proposed.

For the first time, electroluminescence detected in the middle and far infrared ranges from silicon carbide nanostructures on silicon, obtained in the framework of the Hall geometry. Silicon carbide on silicon was grown by the method of substitution of atoms on silicon. The electroluminescence from the edge channels of nanostructures is induced due to the longitudinal drain- source current. The electroluminescence spectra obtained in the terahertz frequency range, 3.4, 0.12 THz, arise due to the quantum Faraday effect. Within the framework of the proposed model, the longitudinal current induces a change in the number of magnetic flux quanta in the edge channels, which leads to the appearance of a generation current in the edge channel and, accordingly, to terahertz radiation. Keywords: silicon carbide on silicon, terahertz emission, electroluminescence, nanostructure, quantum Faraday effect.
