The [111]-oriented InAs/GaSb and GaSb/InAs core-shell nanowires have been studied by the 8 × 8 Luttinger-Kohn Hamiltonian to search for non-vanishing fundamental gaps between inverted electron and hole bands. We focus on the variations of the band-inverted fundamental gap, the hybridization gap, and the effective gap with the core radius and shell thickness of the nanowires. The evolutions of a...

In this paper, the Boundary Element Method (BEM) for 3-D elastostatic problems is studied for the analysis of shell or shell-like structures. It is shown that the conventional boundary integral equation (CBIE) for 3-D elasticity does not degenerate when applied to shell-like structures, contrary to the case when it is applied to crack-like problems where it does degenerate due to the closeness ...

In the modern society and specially in our country discussion of poverty, wealth and social justice are the most important arguments of public and private circles. The most important graphical tools which are used to describe the quantity of centralization like wealth in a society is Lorenz curve. In these situations, most of econometricians measure the economic inequalities. In the discrete ca...

Monodisperse anisotropic particles have tremendous potentials in materials science and engineering (Hosein et al., 2010). As one of this kind of materials, snowman-like particles have drawn a special attention in the aspects of both their synthesis mechanism and applications. In this study, we synthesized micron-sized snowman-like poly(methyl methacrylate) (PMMA) particles via a seed emulsion p...

In this study, ZnO-Sn2S3 core-shell nanorod heterostructures were synthesized by sputtering Sn2S3 shell layers onto ZnO rods. The Sn2S3 shell layers consisted of sheet-like crystallites. A structural analysis revealed that the ZnO-Sn2S3 core-shell nanorod heterostructures were highly crystalline. In comparison with ZnO nanorods, the ZnO-Sn2S3 nanorods exhibited a broadened optical absorption ed...
