In this work, the non-relativistic wave equation via the Schrödinger wave equation under the influence of the Aharonov-Bohm flux field Subject to physical potentials of various kinds is investigated. These potentials are modified Coulomb potential, modified harmonic oscillator potential, the Kratzer-Feus potential, and the Mie-type potential which have wide applications in different branches of physics […]
An E×B plasma is important for various applications including Hall thrusters and magnetic nozzle for long-lasting space propulsion. Such a cross field arrangement in inductively coupled plasma plays vital role in film deposition and etching that are the basic ingredients in semiconductor industries; though in these applications, only the electrons are magnetized which enhance the […]
The nonlinear evolution of the magnetic reconnection and onset of the plasmoid instability are investigated by using 2.5-dimensional MHD simulations when the sheared plasma flow is anti-symmetric on either side of the boundary layer. In particular, we considered a wide range of velocity amplitude of shear flow (V0) (from sub-Alfvénic to level of super-Alfvénic) and […]
Gallium nitride(GaN) is a material with a wide and straight band gap of 3.39eV. This semiconductor has the crystal structure of Wurtzite as one of the most stable phases of matter in environmental conditions. This material and its alloys have a low intrinsic charge carrier density due to their wide band gap, but on the […]
The magnetohydrodynamics model is used to investigate the spatial damping in a Hall thruster beam plasma under the effect of thermal motion and electron beam density. Plasma dispersion equation is derived analytically using the normal mode analysis of the small oscillations. The dispersion equation is solved numerically to find out the damping modes in a […]
We construct solutions to the Kadomtsev-Petviashvili equation (KPI) by using an extended Darboux transform. From elementary functions we give a method that provides different types of solutions in terms of wronskians of order N. For a given order, these solutions depend on the degree of summation and the degree of derivation of the generating functions. […]
In this study, a SiGe (Si(1-X) GeX x=0.1) thin film solar cell structure based on the carbon nanotube charge collector (CNT) is investigated. The addition of the carbon nanotube layer to cell structure has been proven to change aspects of its physical characteristics, specifically the efficiency of the solar cell. This means that CNT can […]
Plasma-material interaction has been a subject of interest for the past several decades due to its importance in various fields of research such as film deposition, surface nitriding, plasma etching, plasma reactors at low-pressure conditions etc. During this interaction, the presence of negative ions further plays a vital role to ease defect-free analysis of soft […]
Thermal plasma treatment is considered as a suitable alternative for the treatment of highly-hazardous wastes such as industrial, radioactive and medical waste. Therefore, a Plasma-Gasification-Melting (PGM) system for treatment of Chemical and Pharmaceutical Wastes (CPW) with a capacity of 1 ton/day is developed using a melting and gasification furnace equipped with two non-transferred thermal plasma […]
Nowadays, there is much extensive research investigating nuclear fusion reaction with D-3He fuel as one of the most essential advanced fusion fuels. One of the most important quantities in fusion is the reactivity. In this work, with consideration of different temperatures for ion and electron (hot ion mode), we intend to study the effects of […]
We have solved the Schrödinger equation for Varshni plus Woods-Saxon potential in N-dimensions within the framework of Nikiforov-Uvarov method by using Greene-Aldrich approximation scheme to the centrifugal barrier term. We obtained the numerical bound state energies for both physical parameters and some diatomic molecules for various values of screening parameter which characterizes the strength of […]
We investigate the asymptotic behavior of the solutions to the Klein-Gordon and Dirac equations using the local spatial averaging approach to Bohr’s correspondence principle in the large principal quantum number regime. The procedure is applied in two basic problems in $1+1$-dimensions, the relativistic quantum oscillator and the relativistic particle in a box. In the harmonic […]
In this study, a 2 kJ plasma focus device of Mather type was employed to grow Copper Oxide (CuO) thin film at room temperature on the glass substrate. The anode of the device was made of Copper alloys. A mixture of oxygen and argon (O2+ Ar) gases was used as the working gas for CuO […]
