The electron, heavy hole free and bound excitons allowed eigen-values and corresponding eigen-functions are obtained numerically by solving one-dimensional time-independent Schrödinger equation. Within the parabolic band and effective mass approximations, the calculations are made considering the coupling of the electron in the n-th conduction subband and the heavy hole in the m-th valence subband under the impacts of the well size and impurity position. The obtained results show clearly that the energy, binding energy and photoluminescence peak energy show a decreasing behavior according to well size for both free and bound cases. Moreover, the optical susceptibility associated to exciton transition is strongly red-shift (blue-shifted) with enhancing the well size (impurity position).</p> Fathallah Jabouti , Haddou El Ghazi, Redouane En-nadir, Izeddine Zorkani, Anouar Jorio Copyright (c) 2021 Fathallah Jabouti , Haddou El Ghazi, Redouane En-nadir, Izeddine Zorkani, Anouar Jorio http://creativecommons.org/licenses/by-nc/4.0 https://journals.aijr.org/index.php/anr/article/view/3754 Wed, 01 Sep 2021 00:00:00 +0000 Nanocomposite Obtained in the Plasma of a Pulsed High Voltage Discharge Using Nickel Electrodes and PTFE https://journals.aijr.org/index.php/anr/article/view/4144 <p>In the plasma of pulsed high-voltage discharge, initiated between nickel electrodes in air, when the fluoroplastic is placed in the discharge gap, powder nanocomposite material has been synthesized. The nanocomposite contains NiF<sub>2</sub> nanoparticles less than 5 nm in size, dispersed in a matrix consisting of carbon and fluorocarbon substances. The carbonaceous substance contains nanoscale disordered graphite-like regions. The fluorocarbon component of the composite contains fragments of PTFE molecules and fluorocarbon molecular fragments that differ in structure from PTFE molecule’s structure. After annealing the composite in air at 773 K, the initial nanocomposite is transformed into a nanocomposite containing nanosized PTFE and nanoparticles of NiF<sub>2</sub> less than 5 nm in size, scattered in a matrix composed of nanographite and low-layer nanosized graphene, after aneling at 1173 K into a material containing NiO nanoparticles less than 10 nm in size. After annealing of the initial nanocomposite in argon atmosphere at 1073 K, the obtained nanocomposite contains Ni nanoparticles with sizes less than 5 nm and carbon and fluorocarbon components. The magnetic susceptibility of the unannealed nanocomposite is investigated. A transition to the antiferromagnetic phase at 73 K was detected. At T = 4K, exchange bias interaction of the AFM / FM type takes place in the composite. There is divergence of the FC and ZFC curves, which can be explained by the presence of a superparamagnetic phase or a spin glass phase in the sample. The field dependences of the magnetic susceptibility measured at T = 300 K show sharp changes that occur at certain values of the magnetic field. Elucidation of the nature of these changes requires additional research.</p> Valerii Georgievich Kuryavyi, Grigorii Aleksandrovich Zverev, Ivan Anatol'evich Tkachenko, Arseny Borisovich Slobodyuk, Andrei Vladimirovich Gerasimenko, Aleksandr Yur'evich Ustinov, Vjacheslav Mihajlovich Bouznik Copyright (c) 2021 Valerii Georgievich Kuryavyi, Grigorii Aleksandrovich Zverev, Ivan Anatol'evich Tkachenko, Arseny Borisovich Slobodyuk, Andrei Vladimirovich Gerasimenko, Aleksandr Yur'evich Ustinov, Vjacheslav Mihajlovich Bouznik https://creativecommons.org/licenses/by-nc/4.0 https://journals.aijr.org/index.php/anr/article/view/4144 Sun, 10 Oct 2021 00:00:00 +0000
