Investigation into the optoelectrical properties of TiO2thin films, deposited by RF magnetron sputtering using powder target

Autor: M. Abaab, I. Ben Jemaa, F. Chaabouni

Publikováno v: physica status solidi (a). 214:1600426

TiO2 thin films were deposited at different deposition times and argon flows, onto glass substrates by radio-frequency (RF) magnetron sputtering technique, using a powder target. The X-ray diffraction analysis shows that the increase in the depositio
