“…A ZnO seed layer was prepared on a substrate by RF magnetron sputtering. [20] We used a c-plane sapphire as a substrate to produce ZnO nanorods with higher orientation and density, as reported previously. [21] A c-plane sapphire substrate was fixed in the chamber of a RF magnetron sputtering system with a sintered ZnO target (99.99 % purity, High Purity Materials).…”

The structure of seed layers has been considered as a significant factor to dictate the subsequent growth of ZnO nanorods. We carefully studied seed layer structures such as crystallinity, surface crystal orientations, and grain sizes to investigate their effect on ZnO nanorod growth during hydrothermal synthesis. The structure of seed layers was changed by controlling their thickness and further annealing treatments at 200-1000 °C. Among several parameters of seed layer structure, the grain size and the surface crystal orientation were found to make a noticeable change in the morphology of ZnO nanorods. Thick ZnO nanorods were produced on large grains while densely aligned products were observed on the seed layer surface with c-axis orientation. In addition, at the early stage of synthesis, we observed ZnO nanorods with a diameter much smaller comparing to the size of grains consisting of poly-and single crystal. This explains that the nucleation of ZnO crystals start on c-axis oriented domains, and they grow in a length favorably and in diameter gradually, resulting in the formation of ZnO nanorods with the integration of tightly aligned products.

First-principle calculations were performed to study the structural, electronic, thermodynamic and thermal properties of ZnS x Se 1−x ternary alloys using the full potential-linearized augmented plane wave method (FP-LAPW) within the density functional theory (DFT). In this approach the Wu-Cohen generalized gradient approximation (WC-GGA) and Perdew-Wang local density approximation (LDA) were used for the exchangecorrelation potential. For band structure calculations, in addition to WC-GGA approximation, both Engel-Vosko (EV-GGA) generalized gradient approximation and recently proposed modified Becke-Johnson (mBJ) potential approximation have been used. Our investigation on the effect of composition on lattice constant, bulk modulus and band gap for ternary alloys shows a linear dependence on alloy composition with a small deviation. The microscopic origins of the gap bowing were explained using the approach of Zunger and co-workers. Besides, a regular-solution model was used to investigate the thermodynamic stability of the alloys which mainly indicates a phase miscibility gap. Finally, the quasi-harmonic Debye model was applied to see how the thermal properties vary with temperature at different pressures.
