Abstract

We grow anatase-TiO$_2$ thin films in the low-temperature range from room temperature (RT) to 300 $^\circ$C by using a reactive DC magnetron sputtering method. In particular, we focused on the dependences of the crystalline properties of TiO$_2$ thin films on the growth temperature. The crystallite size and population were found to increase with increasing temperature, which was revealed by using X-ray diffraction and Raman spectroscopic methods. Using a comparative study based on atomic force microscopy, we also identified that the crystallites in the TiO$_2$ thin films were of high quality.
