Article
This research work studies the structural, electronic and magnetic properties of Ge[Formula: see text]Ti x Te (for [Formula: see text], 0.50, 0.75, 1) compounds in rock-salt structure based on first-principles spin-polarized density functional theory. As it is implemented in WIEN2k code, the full-potential augmented plane-wave method was used in th...

Ab initio calculations are performed to investigate theoretically the structural stability, electronic, magnetic, and elastic properties of dilute magnetic semiconductors Ca0.75TM0.25S (TM = Mn, Co, and Ni). These materials crystallize in the ferromagnetic rock-salt phase and are made by doping the CaS binary semiconductor with transition metals at...

Our aim in this paper is to study the influence of doping with transition metals (TM) on the physical properties of CdS. Thus, the structure stability, half-metallic ferromagnetic, and electronic properties of Cr-, V-, Mn-, Cu-, and Sc-doped CdS, at x = 0.0625 concentration have been investigated using first principle calculations based on the dens...

The overall aim of this study is to investigate theoretically the structural, electronic, and magnetic properties of calcium sulfide (CaS) doped with chromium (Cr) impurity, in order to conduct a new search dilute magnetic semiconductors (DMS) suitable for different applications in electronics and spintronics. For measuring, the physical property o...

The objective of this study is to theoretically investigate the electronic, structural and magnetic properties of calcium sulfide (CaS) doped with transition metal vanadium (V) at various concentrations of this element in the rock-salt phase. All properties of Ca1−xVxS compounds are achieved using the full potential linearized augmented plane wave...

In this work, we studied the properties of vanadium doped binary MgS compound Mg1−xVxS (x = 0.125, 0.25, 0.50 and 0.75) in both ferromagnetic rock-salt and zinc-blende structures. The studied properties are structural, electronic and magnetic. The objective of this study is to explore the new dilute magnetic semiconductor systems. We have used two...

In this paper, we have investigated the structural, electronic, and magnetic properties of magnesium selenium (MgSe) doped with transition metal manganese (Mn) impurity in the cubic diluted magnetic semiconductor (DMS) zinc blende structure. The compounds which we are interested are as Mg1−xMnxSe where x change between 0 and 1 by step 0.25. All pro...

The objective of this work is to predict the structural, electronic, magnetic and elastic properties of Mg1−xTMxS (TM=Mn, Fe, Co and Ni) compound in the zinc blende Ferromagnetic phase using first principal approach. The structural and elastic properties are performed using the generalized gradient approximation proposed by Wu and Cohen(WC-GGA). Ho...

In this paper, we report theoretical investigations of structural, electronic and magnetic properties of ordered dilute ferromagnetic semiconductors Cd1−xFexS with x=0.25, 0.5 and 0.75 in zinc blende (B3) phase using all-electron full-potential linear muffin tin orbital (FP-LMTO) calculations within the density functional theory and the generalized...
Article
In this paper a new method using the combination of Neural Networks and the Newton-Raphson algorithm is developped. The technique consists of the use of the solution obtained by Newton-Raphson algorithm between 0.5 and 2.1eV for pure manganese (Mn) and for the amorphous metallic alloy Al88Mn12, to construct two parts of datasets; the first one is u...
Article
The optical absorption of Al80Mn20 quasi-crystalline alloy is calculated from the reflectivity measurements at normal incidence in the energy range from 0.5 to 6.2 eV, using neural networks method. At the beginning, the sample is prepared in the alternate thin layers stacking form of Al and Mn (Multi-layer) selected thicknesses so as to have a tota...
