摘要


氧化亞銅是一種不昂貴且無毒性之半導體材料,本身為具有 2.1eV 能隙的p 型半導體,且在可見光區吸收係數大等優點,極具太陽 能轉化的潛力,故可應用於太陽能電池以及光觸媒上。本實驗利用電 化學沉積法於不銹鋼基板上鍍製氧化亞銅;透過陰陽離子界面活性劑 當作晶形控制劑,藉以觀察電解溶液(硫酸銅、硝酸銅)在改變電壓及 陰陽離子界面活性劑濃度時,對於氧化亞銅在微觀結構和成相性之變 化。由實驗結果XRD 顯示,陰陽離子界面活性劑(SDS)、(CTAB)會 影響氧化亞銅(111)、(110)平面方向成長。透過SEM 薄膜微觀結構顯 示,不同硫酸銅與硝酸銅溶液隨著陰陽離子界面活性劑濃度的改變將 有四角錐、球狀、花狀、柱狀、正方體不同形態上之變化

Cuprous oxide is an inexpensive and non-toxic semiconductor material itself has a 2.1eV band gap of the p -type semiconductor , and absorption in the visible region the advantages of large , highly potential for solar energy conversion , it can be used in solar cells and photocatalyst on. In the study, cuprous oxide were fabricated on stainless steel substrate by electrochemical deposition, with ionic surfactant,Cetyl trimethylammonium bromide (CTAB) and Sodium lauryl sulfate (SDS) as shape controlled agent. The influence of additives on crystal morphology of Cu2O was observed in potential and doping ionic surfactants’ concentration. The Cetyl trimethylammonium bromide (CTAB) and Sodium lauryl sulfate (SDS) influenced crystal planes in (111) and (110).The SEM investigated that the morphology changes are pyramid shape、 s p he r e – l ik e、flower-leaves、columnar shape and cube.
