本研究以粉末固相燒結法，進行FeSe樣品之製備以及性質之研究並進行FeSe單晶以及磊晶生長實驗。超導材料PbO type-FeSe於2008年8月被發現具有超導性質，且可能為Fe扮演超導電子傳遞關鍵角色而受到重視。其超導特性以及理論機制仍然需要深入的實驗研究來佐證。
為了製備純度較高之PbO type-FeSe樣品，本研究製程條件做系列變化，如溫度、時間，以及樣品成分 (Fe/Se)。研究發現FeSe於750o進行製備可得純FeSe相。文獻得知PbO type-FeSe必須在Se比例較低的的成分組成下生成，本研究實驗Fe：Se為名義成分為1：0.84時具有最佳的PbO type-FeSe。
本研究摻雜不同元素來探討摻雜與超導性質的變化。發現摻雜10%的S可以在不產生相變下提升Tc至12K而原本為7K。進行晶格參數計算，摻雜S產生晶格畸變造成FeSe層狀面(ab平面)縮收。
本研究進行FeSe熔融凝固成核，並於LAO基板上進行磊晶生長。本研究發現使用Sn為助熔劑可以使得FeSe於830oC完全融熔並分佈於基板上。目前研究結果顯示，FeSe於基板上有似磊晶的規則生長。

The focus of this research is to prepare a new superconductive material like FeSe by solid state method and analyzing its superconductivity. The key role of Superconductivity was reported recently for PbO type-FeSe.
In this study was varied with the anneal temperature and time and element ratio(Fe/Se) to make pure phase PbO type-FeSe. The result indicateed that we could get the pure FeSe phases synthesized at 750OC. Other superconducting group reported that when the ratio of Se become less they could get PbO type-FeSe phase. Here we get PbO type-FeSe phase mainly at the ratio Fe:Se 1:0.84 nominally .
Doping is a complex but important subject in superconductor. This research discusses about the effect doping on superconductivity. This research get the result that when doped 10% S can raise the Tc from 7K to 12K without changed the phase. Doping S compress the layer of FeSe(ab plane) by calculating the X-Ray data.
This research try to growth epitaxially on LAO substrate by melting and nucleation method. Using Sn as flux can let the FeSe melt at 830oC and cover over the substrate. We could see some FeSe practices on LAO identically epitaxy.
