Abstract

Titanium oxide ($TiO_2$) thin films were fabricated by unbalanced magnetron (UBM) sputtering. The fabricated $TiO_2$ films were treated by oxygen plasma under various RF powers. We investigated the characteristics of oxygen plasma treatment on the surface, structural, and physical properties of $TiO_2$ films prepared at various plasma treatment RF powers. UBM sputtered $TiO_2$ films exhibited higher contact angle value, smooth surface, and amorphous structure. However, the rms surface roughness $TiO_2$ films were rough, and the contact angle value was decreased with the increase of the plasma treatment RF power Also, the hardness value of $TiO_2$ film as physical properties was slightly increased with the increase of the plasma treatment RF power. In the results, the performance of $TiO_2$ films for self cleaning critically depended on the with the plasma treatment RF power.
