A theoretical investigation on the charge-currents and the induced magnetization of the hydrogen atom with noncentral interaction, immersed in plasma environment, under the influence of spherical encompassing is brought ...
Effect of intense laser and electric fields on nonlinear optical properties of cylindrical quantum dot with Morse potential
(2021)
In this study, the effects of the external static electric field and high-frequency intense laser field (ILF) on the nonlinear optical properties, such as the relative refractive index changes (RRICs) and the total optical ...
Characterization of multilayer Al doping in ZnO
(24/04/2021)
ZnO, ZnO/Al, Al/ZnO/Al, and ZnO/Al/ZnO samples were deposited on c-plane sapphire and Si substrates by radio frequency magnetron sputtering (RFMS) using ZnO target. In order to form doped ZnO:Al thin films, these grown ...
