Zinc oxysulfide nanocrystals with zinc blende phase are synthesized through a wet-chemical method. An affirmation of the crystal structure, elemental homogeneity and phase transformation is obtained by X-ray diffraction and authenticated by electron micrographic studies. Theoretical observations have strongly supported the thermodynamic solubility limit for its (30%) formation. An anomalous ban...

The growth of wurtzite GaAs and InAs nanowires with diameters of a few tens of nanometers with negligible intermixing of zinc blende stacking is reported. The suppression of the number of stacking faults was obtained by a procedure within the vapor-liquid-solid growth, which exploits the theoretical result that nanowires of small diameter ( approximately 10 nm) adopt purely wurtzite structure a...

We report an ab initio study of the mechanical stability of platinum nitride (PtN), in four different crystal structures, the rock salt (rs-PtN), zinc blende (zb-PtN), cooperite and a face centered orthorhombic phase. Only the rs-PtN phase is found to be stable, with a bulk modulus B = 284 GPa. Its electronic density of states shows no band gap making it metallic. The zb-PtN phase does not stab...

Although Boron nitride (BN) is a well-known compound widely used for engineering and scientific purposes, the phase stability of its polymorphs, one most fundamental properties, still under debate. The ab initio determination ground state BN such as hexagonal zinc-blende, difficult because elusive Van der Waals interaction, which plays decisive role in some making quantitative prediction highly...

Transport through zinc blende magnetic semiconductors with magnetic domain walls is studied theoretically. We show that these magnetic domain walls have an intrinsic resistance due to the effective hole spin-orbit interaction. The intrinsic resistance is independent of the domain-wall shape and width and survives the adiabatic limit. For typical parameters, the intrinsic domain-wall resistance ...

The field of topological states in phonon solids have been rapidly developing recent years. This work examined the dispersion a compound Boron Phosphide (BP) with Zinc-Blende structure via first-principle calculation. results show that BP is stable theory and hosts rich signatures its dispersion. Specifically, Weyl quadratic nodal line can be found acoustic branches, triple point contact optica...

Understanding the temperature-dependent hardness of covalent materials is fundamental scientific interest and crucial technical importance. Here we propose a formula for zinc-blende structured based on dislocation theory. Our results indicate that at low temperatures, Vickers primarily modulated by Poisson’s ratio shear modulus, with latter playing dominant role. With an increase in temperature...
