本論文提出了一種獨特且新穎的碳材料，稱為 Carbon paper 係通過熱化學氣相沉積（ TCVD）方法 所合成該種新型碳材 Carbon paper不僅展現和其他碳材一樣良好 的導電性質更是在一些光電領域展現出不容忽視的特性。該 Carbon paper的製備過程非常安全且簡單經過一些量測，這些 Carbon paper在光響應方面 擁有難以忽視的潛力。使用 Carbon paper所製備之光偵測器 測得 112  A的光電流 另外也分別檢測了光電導率以及光響應度，其分別為 1.12 S cm-1 和 112 A W-1 cm-2。後續通過使用氮電漿處理，成功地調變 Carbon paper的光電特性材料中的晶格缺損或缺位以及碳氮原子間新的鍵結有助於Carbon paper的光響應表現。在摻雜後之Carbon paper光偵測器中所量測的最高光電流為 2502  A。與其他碳相關材料之光偵測器的研究結果相比，摻雜後之Carbon paper光偵測器之光導率和光響應度的性能都相對優異不少，分別為 25 S cm-1和 3305 A W-1 cm-2。

Through the thermal chemical vapor deposition (TCVD) method, we synthesized the unique carbonaceous material, called carbon paper. This novel carbon paper not only retains the great conductivity of others carbon materials but also exhibits excellent ability in the optoelectronic field. Moreover, the fabrication of this carbon paper is simple and safe. These carbon papers have great potential for their distinct performance in the photoresponse. The 112  A photocurrent was obtained using pristine carbon paper photodetector. Furthermore, the photoconductivity and photoresponsivity were also measured, which were 1.12 S cm-1 and 112 A W-1 cm-2, respectively. By using nitrogen plasma treatment, the optoelectronic properties of carbon paper was improved apparently. The defects in materials and the bonding between carbon atoms and nitrogen atoms contributed to the photoresponse in carbon paper. The highest photocurrent was 2502  A, which was obtained in the doped carbon paper photodetector. The performances in photoconductivity and photoresponsivity were significant compared with other carbon-relative photodetectors research, the values were 25 S cm-1 and 3305 A W-1 cm-2, respectively.
