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 ...
Watt-level and sub-100-fs self-starting mode-locked 2.4-µm Cr:ZnS oscillator enabled by GaSb-SESAMs
(09/02/2021)
Femtosecond lasers with high peak power at wavelengths above 2 µm are of high interest for generating mid-infrared (mid-IR) broadband coherent light for spectroscopic applications. Cr2+-doped ZnS/ZnSe solid-state lasers ...

Effect of size modulation and donor position on intersubbands refractive index changes of a donor within a spherical core/shell/shell semiconductor quantum dot
(2021/9/24)
In the current study, linear, nonlinear and total relative refractive index changes of a single shallow hydrogenic donor atom confined in semiconductor core/shell/shell quantum dot heterostructure are investigated in detail ...
Effect of the Woods-Saxon Spin–Orbit Term on the Nuclear Spectra: 18O Application
(20/03/2022)
One of the successes in describing the nuclear structure correctly is taking into account the spin–orbit interaction. Thus, single-particle energies and nuclear magic numbers can be obtained accurately. The main subject ...
Estimations of first 2+ energy states of even even nuclei by using artificial neural networks
(Indian Journal of Physics, 2022)
The first excited 2+ energy states of nuclei give much substantial information related to the nuclear structure. All excited states of nuclei are shown regularities in spin, parity, and energy, including these levels. In ...
