Zinc magnesium oxide [Zn1-xMgxO (0 <= x <= 0.2)] nanofibers were grown by solution growth technique on glass substrate having zinc oxide (ZnO) seeds deposited onto them. The films were dense and characterized by strong reflections from (0 0 2) planes followed by reflections from (2 2 0) planes. Band gap varied between 3.14 and 3.75eV with magnesium content varying between 0.05 and 0.20. Photoluminescence (PL) spectra recorded at 10K for ZnO nanorods were dominated by a strong luminescence peak in the UV region at similar to 3.13eV. With the addition of Mg in the ZnO lattice, a low-intensity PL peak started appearing in the blue region (similar to 2.62-2.65eV). The films were also characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR) and Raman measurements. (C) 2008 Elsevier B.V.

Enhanced photodetection properties of GO incorporated flexible PVDF membranes under solar spectrum

E. S. Kadir, R. N. Gayen, M. Pal Chowdhury

Summary: This paper reports the enhanced photodetection capabilities of highly flexible polyvinylidene fluoride (PVDF) membranes incorporated with graphene oxide (GO) when illuminated by the solar spectrum. The addition of a small amount of GO into the PVDF matrix improves the dark current and solar photocurrent, leading to increased photoresponsivity and decreased response time. The flexible PVDF/GO composite membranes exhibit better photocurrent in a bending state, attributed to the piezo-phototronic effect.

Study of AlN growth using AMEC Prismo HiT3 MOCVD reactor

Jianzheng Hu, Long Yan, Ning Zhou, Yao Chen, Xiaoni Yang, Lianqiao Yang, Shiping Guo

Summary: The effect and mechanism of carrier gas velocity, V/III ratio, and carrier gas velocity match on the growth rate of AlN were investigated in this study. The results showed that the growth rate of AlN initially increased with hydrogen flow rate, reached saturation, and then decreased monotonically. The turning point value depended on the equipment and process. By increasing the MO VM, the growth rate of AlN could be improved, but the uniformity deteriorated due to turbulence and loss of uniform boundary layer. High quality AlN films were successfully grown on nano-patterned sapphire substrates with improved crystalline quality and atomic smooth surfaces.

Summary: This study investigates the melting process and nucleation behavior of sodium crystals using molecular dynamics simulation. The results show good agreement between simulated and experimental values for the melting temperature, density, and radial distribution function of sodium.
