臺灣博碩士論文加值系統

本篇論文，我們使用了氫氟酸來製作氟化石墨烯懸浮液，且藉由Raman shift
和XPS 的量測，我們確認了氟化石墨烯的氟化程度。接著調變氫氟酸的濃度和加
熱時間，比較不同參數製作的氟化石墨烯的特性。另外我們同樣比較氟化石墨烯
在經過高溫處理前後，是否會因為高溫而有所變化。
接著藉由C-V 量測、I-V 量測和Lifetime 的量測，研究氟化石墨烯在太陽
能電池或者其他元件上的應用，由C-V 量測，我們發現氟化石墨烯和氧化石墨烯
同樣具有固定負電荷的特性。而在Lifetime 的量測顯示，氟化石墨烯在經過高
溫處理後，對於Lifetime 的提升相當明顯，而太陽能電池大都需要經過高溫處
理，表示氟化石墨烯相當適合應用在太陽能電池的鈍化層上。此外，I-V 的量測
看到，氟化石墨烯具有相當良好的可逆電阻開關效應，這個特性可應用於電阻式
記憶體的製作。

In this paper, we have used hydrofluoric acid to make fluorographene
suspensions. The Raman shift and XPS measurements were used to confirm the
degree of fluorination of fluorographene. We have compared the property of
fluorographene with different parameters including different concentrations of
Hydrofluoric acid and heating time. In addition, we have also compared
fluorographene before and after high temperature treatment.
The C-V measurement, I-V measurement and lifetime measurement were used to
characterize fluorographene to investigate the possible applications on solar cells or
on other device. The CV measurement shows that fluorographene also has negative
fixed charge similarly to that in graphene oxide. In the lifetime measurement,
fluorographene after high temperature treatment displays an obvious promotion of
lifetime. Since the high temperature treatment is necessary for the most of solar cells,
fluorographene may be suitable for applications in the solar cell passivation layer. I-V
measurements show that fluorographene has a fairly good reversible resistance
switching effect, and this feature could be applied to resistive random-access memory.
