This article presents the impact of different radio frequency (RF) power during deposition on the properties of ZnO thin films. The experiments reveal that RF power variation during the deposition process significantly affects the structural, morphological, electrical, and optical properties of the films.
This article presents the impact of different radio frequency (RF) power during deposition on the ZnO thin films properties, deposited using RF sputtering deposition technique. The effect of these process parameters on the structural, morphological, electrical and optical properties are elaborated in detail. The crystalline quality and optical parameters of the films are affected by RF power variation during film deposition. The film's crystal quality was reasonably decent with the RF power reaching 100 W. For a 5 mu m x 5 mu m scan area, the RMS roughness value changed from 1.29 to 3.22 nm as the P-RF increases from 50 to 100 W. FESEM images depicts the decrement in grain size of ZnO thin film as RF power increases. When the RF power was varied during deposition, both mobility and carrier concentrations changed. Blue shift was observed in UV emission with increasing RF power.
