2009 WILEY-VCH Verlag Gmb Synthesis of materials with a desired crystal structure is a major challenge in materials engineering. Single-crystal thin films grown by epitaxy typically adopt the same crystal structure as that of their substrates. Here, we report on the observation of a wurtzite InAs thin-film structure on a zinc-blende InAs substrate. Electron-backscatter diffraction (EBSD) and tr...

Nanostructured zinc oxide (ZnO) materials have received considerable interest from scientists due to their remarkable performance in electronics, optics and photonics. ZnO nanoparticles were synthesized by co-precipitation method. ZnO nanoparticles were synthesized using Zn(NO3)3 and K2CO3 precursors. The structure of the obtained product was confirmed by the powder X-ray diffraction (XRD) anal...

The ZnO/SiO2 semiconductor nanophotocatalysis was synthesized via sol-gel method. Also, theplatinum particles were loaded on the ZnO/SiO2 nanoparticles by photoreductive method. Thestructure of catalyst was confirmed by X-ray diffraction (XRD), scanning electron microscopy(SEM) andfourier transform infrared spectroscopy (FT-IR). The XRD patterns of ZnO particlesdisplayed the nanoparticles have ...

Cu2ZnSnS4 is a promising, versatile and inexpensive quaternary semiconductor with suitable optoelectronic properties for solar energy conversion. In this work, we report the synthesis of CZTS nanocrystals (NCs) using low-cost homemade hot-injection method. Oleylamine was used as both binder stabilizer NCs during growth process. Detailed investigation influence sulphur concentration reaction tem...

In the present study, we provide useful data related to one of most promising materials in thin-film solar cell technologies: Cu2ZnSnS4 (CZTS) kesterite structures. Sol-gel spin coating and chemical bath deposition methods were used fabricate further investigate Mo/CZTS/CdS/ZnO/AZO heterostructures. order examine crystal structure samples, Raman scattering measurements using two excitation wave...

Zinc oxide (ZnO) and samarium (Sm) doped ZnO nanoparticles (NPs) were synthesised by solution combustion approach using citric acid as fuel. The formation of hexagonal wurtzite structure pure Sm powder was prepared confirmed x-ray diffraction (XRD). formation, morphological elemental analysis analysed XRD, Raman spectra, scanning electron microscopy (SEM) xray fluorescence spectroscopy (XRF). r...

ZnO nanocrystalline powder was successfully synthesized via co-precipitation method coupled with high annealing treatment. X-ray diffraction analysis revealed that the NPs have a pure hexagonal wurtzite structure mean crystallite size of approximately 59 nm. FESEM observations along EDS indicated formation fine particles in nanoscale regime, shape and purity. Both Raman photoluminescence charac...
