概要(目的・用途・実施内容)/ Abstract (Aim, Use Applications and Contents)
Using thin film X-ray reflectivity and diffraction setup to analyze the growth conditions of niobium oxide and its properties.
実験 / Experimental
Si wafers and sapphire wafers were cut into pieces by using dicing saw. Pulsed laser deposition (PLD) was used to deposit niobium oxide films on the substrates at different temperatures and different oxygen partial pressure. Films thickness and crystallinity properties were examined by Spectroscopic Ellipsometer, X-ray reflectivity and X-ray diffraction. We used optical lithography and e-beam deposition methods to pattern electrodes on the films and for studying electronic properties.
結果と考察 / Results and Discussion
By measuring the thickness of oxide films, the deposition rates by using PLD with varied temperature and oxygen pressures were confirmed. X-ray diffraction characterization reveals good crystallinity properties of the oxides. The electrical conductivity of the as-grown films was also obtained by measuring the devices with different oxide channel lengths.
