The effect of structure parameters and static electric field on the nonlinear optical properties of triple InGaAs/GaAs quantum well
(ScienceDirect, 2023)
Optical properties of In x Ga 1-x As/GaAs triple QW are studied for different quantum well thicknesses and external electric fields. The effective mass approximation is used to calculate the band alignment of the structure. ...
Influence of structural variables and external perturbations on the nonlinear optical rectification, second, and third-harmonic generation in the InP/InGaAs triple quantum well structure
(Springer, 2023)
The InP/InGaAs triple quantum well (TQW) structure is of significant interest to researchers studying new generations
of semiconductor optoelectronic devices, as it offers valuable opportunities for controlling and enhancing ...
High harmonic generations in GaAs/AlGaAs superlattice: Effect of electric and magnetic field
(Elsevier, 2023)
In this study, we have examined the nonlinear optical rectification (NOR), the second harmonic generation
(SHG), and the third harmonic generation (THG) coefficients of the AlxGa1-xAs/GaAs superlattice with a periodically ...
High harmonic generations triggered by the intense laser field in GaAs/ AlxGa1-xAs honeycomb quantum well wires
(Elsevier, 2023)
Under constant electric and magnetic fields, the potential profile of the honeycomb quantum well wire (HQWW) is studied for varying intense laser fields to trigger and optimize high harmonics (nonlinear optical rectification, ...
Comparison of Particle Shape, Surface Area, and Color Properties of the Calcite Particles Ground by Stirred and Ball Mill
(2023)
Since the particle size, shape, specific surface area, and purity of the ground calcium carbonate (GCC) decide its usability in the paper, paint, and plastic industries, the effect of grinding is important. However, the ...
