TL;DR: Using the density functional theory of electronic structure, the anisotropic dielectric response of bulk black phosphorus subject to strain was studied in this article, and it was shown that a small compressive or tensile strain, exerted either perpendicular or in the plane to the black phosphorus growth direction, efficiently controls the epsilon-near zero response and allows perfect absorption tuning from low angle of the incident beam.

TL;DR: In this paper, a six-band k∙p theory for wurtzite semiconductor nanostructures with cylindrical symmetry is presented, without the need for the axial approximation.

TL;DR: In this paper, a theoretical study of axisymmetric vibrations of solid circular and annular membranes with continuously varying density has been presented, and exact solutions are found for two families of functional dependencies of the membrane density with respect to the cylindrical radial co-ordinate.

TL;DR: In this paper, an exact method for calculating eigenmodes and eigenfrequencies for an acoustic enclosure (AE) defined by two confocal parabolic cylinders and two plane surfaces using parabolic cylinder coordinates is presented.

TL;DR: In this paper, relativistic linear-muffin-tin-orbital calculations of the electronic structure of zinc-blende-type silicon carbide (3C-SiC) within the local density approximation are presented.
