摻雜銻之p-type氧化鋅薄膜特性分析

The Study of Sb-doped p-type ZnO Films

指導教授 : 王耀德

摘要


本論文是以超音波噴霧熱解法藉由銻之摻雜,成功地在玻璃基板上成長p-type ZnO薄膜。實驗主要分兩部份,第一個部份是薄膜樣品之製作,第二部份是對製作好的薄膜加以分析其晶格結構、電性結果和能隙變化。 從XRD分析中,隨著摻雜濃度的提升,(101)peak會向低角度位移;而在霍爾量測分析中,顯示在製程溫度為550℃時,推論摻雜濃度為2.2at.%時,會有最佳電性結果,分別有最高載子濃度7.13×1018 cm-3、最低電阻率0.05 -cm與遷移率17.52 cm2/Vs。因此,本實驗結果顯示利用裝置簡單、成本較便宜的超音波噴霧鍍膜系統,以單純的銻摻雜可在玻璃基板上成功地成長出p-type ZnO薄膜。

In this theis, the p-type ZnO films were grown on the glass substrates by ultrasonic spray pyrolysis method. The experiment divided into two parts mainly. The first part is about the deposition of the thin films. The second part is the measurements and analysis of these deposited ZnO thin films. The structure, electronic properties and the changes of the band gaps with different fabrication parameters were analized. Results of X-ray diffraction reveal that the Sb atoms were successfully occupied the Zn sites, and make the(101) peak shift to lower value. The Hall-effect measurement shows that we obtained the best electronic results when the grown temperature was at 550℃. The ZnO with Sb-doping of 2.2at.% exhibits a high hole concentration of 1.73 × 1018 cm−3 , low resistivity of 0.05 -cm and high mobility of 17.52cm2 /Vs. In conclusion ,the Sb-doped p-type ZnO films were successfully grown by ultrasonic spray pyrolysis method.
