![عکس صفحه اول مقاله: Room temperature radio-frequency plasma-enhanced pulsed laser deposition of ZnO thin films Room temperature radio-frequency plasma-enhanced pulsed laser deposition of ZnO thin films](/preview/png/5363842.png)
In this study, we compared the crystalline structures, optical properties, and surface morphologies of ZnO thin films deposited on silicon and glass substrates by conventional pulsed laser deposition (PLD) and radio-frequency (RF) plasma-enhanced PLD (RF-PEPLD). The depositions were performed at room temperature under 30-100Â mTorr pressure conditions. The RF-PEPLD process was found to have deposited a ZnO structure with preferred (0Â 0Â 2) c-axis orientation at a higher deposition rate; however, the RF-PEPLD process generated more defects in the thin films. The application of oxygen pressure to the RF-PEPLD process reduced defects effectively and also increased the deposition rate.
⺠ZnO thin film was deposited by RF. plasma-enhanced pulsed laser deposition. ⺠The depositions were performed at room temperature under low-vacuum conditions. ⺠The oxygen pressure reduced defects effectively and increased the deposition rate.
