Summary:	本論文研究以 RF 磁控共濺鍍法成長Zn1-xMnxO 稀磁性半導體薄膜，探討不同的製程氣氛(如：Ar、Ar+N2、Ar+O2)以及Mn靶濺鍍功率等實驗參數下，Zn1-xMnxO 薄膜在晶體結構、表面型態、光學性質、電性以及磁性等物理性質的變化，並希望能對於 Zn1-xMnxO 稀磁性半導體薄膜的磁性變化有所了解。從實驗結果顯示，當Mn 的濺鍍功率(PWMn)≧15 W 時，Zn1-xMnxO 薄膜中會出現Mn2O3 、Mn3O4 ，但在Ar+O2 的製程氣氛下所製作之Zn1-xMnxO 薄膜中並無發現此氧化物相。在Ar和Ar+N2 的製程氣氛下所製作的 Zn1-xMnxO 薄膜，光能隙會隨Mn 濃度增加而逐漸下降，此與氧化物的出現有關。此外，Zn1-xMnxO 薄膜的電阻率很高，且載子密度相當低，幾乎是絕緣性的。在製程氣氛為 Ar 和Ar+N2時，未摻雜的ZnO薄膜有較明顯的鐵磁訊號，而在 Ar+O2 製程氣氛下的ZnO 薄膜沒有鐵磁性。在300 K 時，在Ar、Ar+N2下所製作的Zn1-xMnxO薄膜，隨著PWMn的增加，飽和磁化量是上升的；而在Ar+O2下製作的Zn1-xMnxO 薄膜，飽和磁化量有些微下降。10 K 時，隨著PWMn的增加，所有Zn1-xMnxO 薄膜樣品的順磁性有增強的趨勢。 In this thesis, we report effects of different growth atmospheres, such as Ar、Ar+N2 and Ar+O2, and different sputtering powers of the Mn target on the crystal structural, surface morphological, optical, electrical, and magnetic properties of Mn-doped ZnO films deposited using the magnetron co-sputtering method. The aim of this work is to examine the possibility, as well as to realize the mechanism, of room-temperature ferromagnetism in Mn-doped ZnO films. Our results show that as the PWMn is higher than 15 W, little amounts of the Mn2O3 and Mn3O4 phases start to appear in the Mn-doped ZnO films grown under the Ar atmosphere. It is worthy noting that for the Mn-doped ZnO films grown under the Ar+O2 atmosphere, no Mn2O3 and Mn3O4 phases can be observed. For the Mn-doped ZnO films gown under the Ar or Ar+N2 atmosphere, the optical bandgap will increase with increasing the Mn content possibly due to the existence of Mn2O3 and Mn3O4 phases. In addition, all of the Mn-doped ZnO films are almost insulating due to a high electrical resistivity and a low carrier density. The pure ZnO films grown under the Ar or Ar+N2 atmosphere are ferromagnetic, while those grown under the Ar+O2 atmosphere have no ferromagnetic response. With increasing the PWMn, the saturation magnetization of the Mn-doped ZnO films grown under the Ar or Ar+N2 atmosphere will increase, while the saturation magnetization of those grown under the Ar+O2 atmosphere will decrease, at RT. In particular, all of the Mn-doped ZnO films exhibit a stronger paramagnetic signal at 10 K as the PWMn is increased.
