Microstructural analysis of Nb-doped anatase TiO 2 transparent conductive films by transmission electron microscopy

We investigated microstructures and transport properties of Nb-doped anatase TiO2 (TNO) films deposited by two methods: sputtering and pulsed laser deposition (PLD).We found that working pressure (Pw) of sputtering has a significant influence on both microstructures and transport properties. Cross-sectional observation by transmission electron microscopy revealed that lowered Pw improved homogeneity in the microstructure. This finding indicates that the inhomogeneous microstructure of the sputtered TNO films is not due to sputtering damage but to fluctuation in mass density. A sputtered film deposited at Pw = 0.50 Pa exhibited homogeneous microstructure and high Hall mobility comparable to those of PLD films.
