抄録

Rutile (110) rich TiO2 films were prepared at a low temperature by introducing He gas in reactive sputtering. The optimum gas pressure ratio providing the richest rutile composition to deposited film was He : O2 : Ar =1 : 0.42 : 2.39 for a total gas pressure of 0.27 Pa. The rutile (110) phase was grown by the reaction between sputtered Ti and active oxygen species O2+, O*. The former is generated by the penning ionization of oxygen molecules by He*. The latter is produced from the decomposition process of O2+. This film indicated the greatest crystalline size and the highest refractive index. Furthermore, the film consists of the uniform crystalline sizes of 2030 nm.
