| 摘 要： | 采用射频磁控溅射法在玻璃衬底上室温沉积不同钽掺杂浓度的氧化锌透明导电薄膜.并对其结构和电学特性进行分析.对衍射峰的分析说明Ta元素以替位Zn元素的形式溶入ZnO晶格中形成了固溶体.当钽掺杂比例从0 wt%增加到10 wt%,晶格常数从0.5242 nm增加到0.5314 nm,表明薄膜中存在平行于c轴方向的张应力.薄膜沿c轴的晶粒尺寸在9.4~13.5 nm之间.薄膜的电阻随着掺杂比例增加首先显著下降,当掺杂比例为5 wt%时,薄膜最小电阻率为7.81×10-2Ω.cm,进一步增加掺杂比例到10 wt%,电阻率增大为1.25×10-1Ω.cm. |

| Abstract: | Tantalum-doped zinc oxides transparent conducting films with different Ta fraction were prepared by RF magnetron sputtering on glass substrates at room temperature,and their microstructure as well as electrical properties were characterized and analyzed.X-ray diffraction analysed suggested that Ta had been incorporated into ZnO lattice and substituted Zn in the hexagonal lattice.With the increase of the Ta2O5 content from 0 to 10 wt%,the lattice constants of ZnO increased from 0.524 2 to 0.531 4 nm and the ... |
