Effects of external fields on the nonlinear optical rectification and second harmonic generation of GaAs/GaAlAs zigzag quantum well
(2023)
For the first time, the impact of externally applied static electric and magnetic field on the nonlinear op- tical rectification (NOR) and second harmonic generation (SHG) coefficients of GaAs/GaAlAs zigzag quan- tum well ...
Modeling and simulation of the influence of quantum dots density on solar cell properties
(Springer, 12 Şubat 2)
Based on the finite element method using the FEniCS computing platform and python programming, we solve the Schrödinger equation within the effective mass approximation. Its solution gives us the necessary energy for an ...
Synthesis and characterization of molybdenum trioxide with an orthorhombic crystal structure for supercritical water gasification application
(01.03.2023)
Supercritical water (SCW) catalytic gasification is promising for the production of synthetic gas from biomass. However, maintaining the activity of heterogeneous catalysts under high pressure and hydrothermal conditions ...
Evaluation of characteristics of raw tea waste‑derived adsorbents for removal of metals from aqueous medium
(01.06.2023)
Chemical modification and microwave activation are cost-effective and eco-friendly engineering methods to improve biochar’s physicochemical and adsorption performance. Therefore, a series of biochars samples was produced ...
Linear and nonlinear optical properties of CdSe/ZnTe core/shell nanostructures with screened modified Kratzer potential
(2023)
In this work, we have theoretically examined the linear, nonlinear and total refractive index changes (RICs) and optical
absorption coefficients (OACs) between the ground (1s) and the first excited state (1p) of CdSe/ZnTe ...
Direct co-deposition of binder-free Cu-biochar-based nonenzymatic disposable sensing element for electrochemical glucose detection
(01.11.2023)
This work is the first attempt to incorporate biochar on a pencil graphite electrode via one-step electrodeposition as a rational route for refining a copper-based biosensor for a high-performance nonenzymatic electrochemical ...
Techno-economic analysis of ground source heat pump powered by hybrid photovoltaic–wind–diesel systems in a temperate climate region
(Springer Nature, Ağustos 20)
As in many European countries, Turkey’s foreign energy dependency is quite high. Reducing foreign dependency on energy on a national basis is possible by developing efficient systems and increasing the use of renewable ...
The nonlinear optical properties of "12-6" tuned GaAs/GaAlAs double quantum well under the external fields
(Springer, 22 Şubat 2)
We have studied the linear and nonlinear optical properties of 12-6GaAs/Ga1-xAlxAs double quantum well heterostructure under different external fields’ effects such as electric, magnetic and intense laser fields. We also ...
Structural, dielectric and transport properties of NaxFe1/2Mn1/2O2 (x=1 and 2/3)
(13.06.2023)
NaxFe1/2Mn1/2O2 (x = 1 and 2/3) layered oxides were prepared by an improved solid-state synthesis method. The XRD analysis confirmed the high purity of these samples. The Rietveld refinement of the crystalline structure ...
Effects of external electric and magnetic field on the nonlinear optical rectification, second, and third-harmonic generations in GaAs/AlGaAs asymmetric triple quantum well
(2023)
In this paper, we theoretically investigate the nonlinear optical rectification (NOR), second-harmonic generation (SHG),
and third-harmonic generation (THG) coefficients of an AlGaAs/GaAs asymmetric triple quantum well ...
