Sol-gel procedure was taken into consideration to produce ferrite series with chemical formula MnYbyFe2-yO4 y = 0.00 0.10 (step 0.025). Structural, electrical and magnetic aspects of ytterbium (Yb) switched Mn-ferrites were the main focus. Every sample exhibited cubic phase spinel assembly. Exchange iron in system produced enlargement coercivity while abridgment remanence saturation magnetization. Involvement Yb ion assembly led reduction both real imaginary constituents permittivity. The...
The double perovskites are promising for solar cells and other optoelectronic applications. In this article, the optoelectronic, transport characteristics of new Ga2PdCl6, Ga2PdBr6, Ga2PdI6 addressed. structural thermodynamic stabilities have been addressed by tolerance factor, positive frequency phonon dispersion. reported band gaps 2.05 eV, 1.60 eV 0.80 which increases their performance cells.

We investigate optical absorption coefficients and changes in the refractive index single- double-step GaAs/AlGaAs quantum wells under influence of magnetic, electric, intense laser fields. For single-step wells, increasing intensity external electric fields induces a red-shift total coefficient change increases their amplitudes; however, magnetic field generates blueshift index. transition energy between ground first excited state is strongly decreased. In addition, incur blue shift when...
Abstract Herein, the electronic, optical, mechanical, and transport properties of a double perovskites Cs 2 TeX 6 (X = Cl, Br, I) are explored with focus on solar cell thermoelectric applications by density functional theory (DFT). The feasibility structural, thermodynamic, elastic stabilities is arbitrated tolerance factor, formation energy, constant, respectively. Further, Poisson Pugh’s ratio display ductile behavior studied compounds. From electronic analysis, it revealed that bandgap...
