AbstractRadiofrequency (RF) plasma polymerization is a convenient thin film deposition process as it facilitates the synthesis of polymer films with stable physico-chemical properties suitable for various applications in microelectronic, optical, and biomedical fields. The unique properties of these plasma polymerized films as compared to the conventional ones are strongly related to the proper adjustment of […]
AbstractAbstractExperiments on proton-deuteron radiative capture and the inverse reaction, the photo-disintegration of 3He, performed since 1963, up to the intermediate energies are reviewed. Differential cross sections in the center-of-mass system for the radiative capture (θγc.m.=90°) and the inverse reaction (θpc.m.=90°) as a function of photon energy are presented. The experimental data are compared with a […]
AbstractWe investigate the excitation behavior of a repulsive impurity-doped quantum dot induced by the simultaneous oscillations of the impurity coordinate and spatial stretch of the impurity domain. We have considered repulsive Gaussian impurity centers. The ratio of two oscillations (η) has been exploited to understand the nature of the excitation rate. Indeed, it has been […]
AbstractThe use of glancing angle deposition technique provides opportunities for the deposition of sculptured nanostructures of different shape. The optical properties of such nanostructures that are a function of the shape of these nanostructures may be investigated, using the discrete dipole approximation theory which is an appropriate method for solving the light scattering problem from […]
AbstractIn this paper, we first review some aspects of the f(R) gravity, and then the concept of the torsion of space-time due to metric-affine formalism in f(R) gravity is studied. Within this formalism, in which the matter action is supposed to be dependent on the connection, we achieve interesting cases including nonzero torsion tensor. Then […]
AbstractIn 2006, some authors determined that the triboluminescence (TL) of manganese-doped zinc sulfide (ZnS:Mn) increases with increasing impact velocity. In 2011, the authors discovered a method of synthesizing europium dibenzoylmethide triethylammonium (EuD4TEA) that produced TL 106% greater than ZnS:Mn. In fact, this material is bright enough to be seen in daylight. This paper investigates the […]
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 […]
