Terahertz radiation finds applications in medical science, spectroscopy, security screening, communication, etc. There are several methods that focus on the interaction of lasers with plasma, and laser beating process is an effective scheme for the Terahertz radiation generation. In this scheme, a resonance between the beating frequency and plasma frequency needs to be achieved. In […]
Silver Oxide (AgO) thin films were prepared by using a cylindrical direct current reactive magnetron sputtering system at 10-5 torr initial pressure on BK7 glass substrate. Samples deposited for 3, 5 and 7 minutes. Surface characterization of AgO thin films in the nanometer scale can be accurately determined using the atomic force microscopy (AFM) and […]
The aim of the paper is to study the electron spin direction dependence on momentum due to the presence of Rashba spin-orbit coupling in the pseudo-gap phase of Bi2212 bilayer. The non-trivial spin texture in k space is found tuneable by electric field. The dependence is reported earlier by a group of workers in a spin […]
Charged particle acceleration is the subject of great interest because of its applications in various fields such as thermonuclear fusion, nuclear physics, radiation generation, coherent harmonic generation, probing materials, medical science, food preservation, etc. The particle acceleration is usually done by interacting the particles with strong electric fields. Since the magnetic field diverts the particle […]
Triply heavy Ω_ccb baryon is considerable theoretical interest in a baryonic analogue of heavy quarkonium because of the color-singlet bound state of three heavy quark (c, b) combination inside. In this paper, we will discuss Ω_ccb baryon in the nonrelativistic quark model based on the ansatz approach in Hypercentral Constituent Quark Model. The masses of […]
In this paper, using finite difference method, the effect of adding a p-layer at the back of a metal-semiconductor-metal (MSM) photodetector (PD) on the spatial electric charge distribution and the transient response of the device is numerically studied. To this aim, the fundamental equations of the semiconductor device, i.e., two current continuity time-dependent equations have […]
Preparation of graphene decorated MOF-5 nanocomposite by pulsed laser ablation (PLA) method in liquid environment has been investigated for the first time. Firstly, MOF-5 nanostructures were synthesized by irradiating a high-purity zinc (Zn) plate in dimethylformamide (DMF) solution containing terephthalic acid ligand with Nd:YAG pulsed laser. Using the fundamental wavelength of Nd:YAG laser at 1046 […]
A simple method, to rationalize anisotropic X-ray line widths of deformed FCC metallic samples is presented. The method is based on normalized Diffraction Elastic Constant ratio (DECR) within the framework of Stokes Wilson approximation and Gaussian microstrain distribution. The observed dispersion in classical Williamson-Hall plot was significantly reduced if DECR based correction was applied to […]
Vacancies occur naturally in all crystalline materials. A vacancy is a point defect in a crystal in which an atom is removed at one of the lattice sites. The defect could be imported during the synthesis of the material or be added by defect engineering. In this paper by employing the density functional theory as […]
During helium transforms into heavier elements, both of 6Li radiative capture reaction and its breakup occur in the stars. 6Li radiative capture reaction and its inverse have been studied using Effective Field Theory (EFT), up to next to leading order (NLO). The deuteron-alpha reaction and the photodisintegration rates of the 6Li(γ,α)d reaction have been calculated. […]
