Hafnium oxide mixed tantalum oxide (HTO) and Zirconium oxide mixed tantalum oxide (ZTO) layers were deposited on chemically cleaned p-Si substrate using RF magnetron sputtering technique. The oxide/Si stacks were annealed in oxygen for 30 minutes at 400 °C as on initial investigation. Both composition and structural properties were absolutely interesting to move further for electrical measureme...

In this study, we show from helium (He) plasma irradiation to tantalum and iron surfaces that morphology changes in nanoscale occur on the both metals. In particular, from systematic irradiation experiments, it is identified that fuzzy nanostructures are grown on the both metals. The necessary conditions for the morphology changes are discussed based on the experimental results in terms of the ...
