Wurtzite structured ZnS nanoribbons have been synthesized by a catalyst-free solid–vapor deposition technique. The nanoribbon has a saw-teeth shape, and the nanosaw is formed by a two-step process: a fast growth along a-axis forms the body of the saw; a subsequent growth along c-axis creates the teeth. The one-sided teeth structure is suggested to be the self-catalyzed growth of the Znterminate...

Here we report on detailed studies of the magnetic properties wurtzite (Ga,Mn)As cylindrical shells. Ga$_{0.94}$Mn$_{0.06}$As shells have been grown by molecular beam epitaxy at low temperature as a part multishell cylinders overgrown (Ga,In)As nanowires cores, synthesized GaAs (111)B substrates. Our clearly indicate presence ferromagnetic coupling, which despite reasonably high Mn contents 6\%...

in present work, we have calculated the electronic properties including density of states (dos) and electron density for gan, inn and in wurtzite phase for x=0.5. the study is based on density functional theory (dft) with full potential linearized augmented plane wave method (fp-lapw) by generalized gradient approximation (gga-pbesol) for calculating electronic properties. in this report we con...

Abstract The ferroelectricity of wurtzite, Sc x Ga 1− N ( = 0.35–0.44), was demonstrated in a metal–ferroelectric–metal capacitor. remanent polarization P r ) obtained from positive-up negative-down measurements high, exceeding 120 μ C cm −2 . coercive field E c 0.44 0.56 approximately 3.6 MV −1 at 300 K, which decreased to 3 473 K. We observed that regardless the host material, concentration g...
