The Nernst effect has been theoretically studied in compositional superlattice in the presence of a strong electromagnetic wave. Using the quantum kinetic equation for electrons with two cases electrons-acoustic phonons scattering and electrons-optical phonons scattering, we obtained the analytic expression of the Nernst coefficient and kinetic tensors as a function of the magnetic field, temperat...... hiện toàn bộ
Radioelectric field in semi-parabolicplus semi-inverse squared quantum wells has been studied in the presence of a linearly polarized electromagnetic wave. By using quantum kinetic equations for electrons in the case of electrons – optical phonons scattering, the analytical expression for the Radioelectricfield was obtained as a function of the frequency, the amplitude of the linearly polarized el...... hiện toàn bộ
Cuprous oxide (Cu2O) and Au-Cu2O core-shell nanoparticles were successfully synthesized using the chemical reduction method. The morphology of the synthesized pure Cu2Oparticles can be controlled by varying the amount of reducing agent NH2OH.HCl. Due to their similar crystal structure and relatively small lattice mismatch Cu2O particles are nucleated and locally undergo an epitaxial growth on the ...... hiện toàn bộ
Let be non-negative integers and be an -module such that is finitely generated for all and for all , where is a class of modules. We hence prove that (1) if then is -cofinite for all ; (2) if and is finitely generated for all , then is -cofinite for all . These extend the results of Khazaei-Sazeedeh [10, Thm 2.10, Thm 2.11] fo...... hiện toàn bộ
In this work we proposed a simple method to determine the coordinate of interface of two-component Bose-Einstein condensates (BECs) in double parabola approximation (DPA) under Neumann boundary conditions. Based on this idea, the static properties of BECs have been investigated totally in DPA.
In this work, three TiO2 anatase phase samples, labeled as S1, S2, and S3, were synthesized using varying titanium precursors, solvents, and conditions to compare their photocatalytic performances. The structural and morphological properties of the synthesized samples were characterized through X-ray diffraction (XRD), Raman scattering, field emission scanning electron microscopy (FESEM), and tran...... hiện toàn bộ
