Electrical properties of Mg x Zn1−x O thin films deposited by using RF magnetron co-sputtering with ZnO and Mg0.3Zn0.7O targets
We successfully deposited hexagonal wurtzite Mg x Zn1−x O (0 ≤ x ≤ 0.18) films on Si substrates by using RF magnetron co-sputtering with ZnO and M...

Effects of in content on the microstructure and the roughness of ZnO:In films
We investigated the changes in the preferred orientation and microstructure of ZnO:In films with increasing In content. ZnO and ZnO:In films with In contents of up to 50 at.% were deposited on Si (111) substra...

Stability characteristics of gallium-doped zinc-tin-oxide thin-film transistors fabricated using a sol-gel method
We investigated the incorporation of Ga into zinc-tin-oxide (ZTO) thin-film transistors (TFTs) and assessed the TFTs’ electrical and stability properties. The Ga-doped ZTO (ZTO:Ga) thin films were deposited on...

Effects of Mg incorporation by co-sputtering into the ZnO channel layer of thin-film transistors
We fabricated a series of ZnO-based thin-film transistors (TFTs) in which the Mg composition ratio in the active layer was varied by controlling the RF power applied to the ZnO and the Mg0.3Zn0.7O targets. Mg ...

Effect of buffer layers on the structural properties of PLD-grown Mg0.5Zn0.5O films on c-sapphire
This study investigated the growth conditions required for growing single-phase hexagonal Mg0.5Zn0.5O epitaxial thin-film layers over a variety of buffer layers, including ZnO, MgO, or Mg x ...

Effect of reactive gases in an atmospheric-pressure plasma for dye adsorption on ZnO nanorods
In this study, ZnO nanorods (NRs) were grown on F-doped SnO2 (FTO)/glass substrate by using a chemical bath deposition (CBD) method. The NRs were crystallized well. The surfaces of the NRs were modified using an ...

Nanopattern fabrication via AP-UVO exposure of a self-organized block copolymer
Block copolymers were used to achieve nanoscale patterning. Block copolymers, particularly polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA), produce patterns from which one block polymer may be selectiv...
