使用角度擴散Ｘ光繞射 (angle-dispersive Ｘ-Ray diffraction, ADXRD) 及拉曼光譜 (Raman spectroscopy) 探討磷化銦摻雜鐵(InP:Fe) 及磷化銦摻雜鋅 (InP:Zn) 高壓下物理特性。摻雜機制的不同造成壓力對InP:Fe 及InP:Zn有不同程度的影響。另外，透過Ｘ光吸收近邊緣結構(Ｘ-Ray absorption near-edge structure, XANES)，確認InP:Fe中鐵的氧化價數為三價。
結果顯示，InP:Fe及InP:Zn在高壓下皆由閃鋅礦結構 (zinc-blende) 轉變為氯化鈉 (rock-salt) 結構並金屬化。由ADXRD數據發現InP:Fe與InP:Zn 相轉變開始壓力分別為8.2(2)和8.6(1) GPa，InP:Fe閃鋅礦結構與氯化鈉結構重量百分率交換壓力與相變結束之壓力分別為10.4(1)及16.0(2) GPa皆較InP:Zn的9.2(1)及14.1(2) GPa高。InP:Fe及InP:Zn拉曼光譜所觀察相變壓力同為8.8(1) GPa，但InP:Fe金屬化壓力為11.6(2) GPa較InP:Zn之14.5(2) GPa低，此因摻雜機制與摻雜元素不同所造成。InP:Fe為鐵三價鐵取代銦的位置與磷鍵結。InP:Zn之摻雜機制為鋅不取代磷的位置而與磷化銦中磷位置的空缺(vacancy)形成鍵結。

Using ADXRD (angle-dispersive Ｘ-Ray diffraction) and Raman spectroscopy, discussed physical properties of Iron doped indium phosphide (InP:Fe) and Zinc doped indium phosphide (InP:Zn) under high pressure. Because different doping mechanism, cause the pressure have different degrees of impact on InP:Fe and InP:Zn. In addition, Using XANES(Ｘ-Ray absorption near-edge structure) to confirm the valence of Iron is trivalent ions forming ionic bonds with phosphorous in InP:Fe. The results showed that both the InP:Fe and InP:Zn are transform from zincblende structure to rock-salt structure and metallic under high pressure. Through the ADXRD data can found the begin phase transition pressure is almost the same with InP:Fe and InP:Zn, at 8.2(2) GPa and 8.6(1) GPa, respectively. The Weight Fraction change pressure and phase transition finish pressure of InP:Fe is at 10.4(1) and 16.0(2) GPa which is higher than InP:Zn at9.2(1) and 14.1(2) GPa. In Raman spectroscopy can observed the begin phase transition pressure of InP:Fe and InP:Zn is the same at 8.8(1) GPa, but the transition to metallic phase pressure of InP:Fe is at 11.6(2) GPa which is lower than InP:Zn at 14.5(2) GPa, the result is because of the different doping mechanism and dopping element. The doping mechanism of InP:Fe is that the iron forming trivalent ions and replace the indium to form ionic bonds with phosphorous. The doping mechanism of InP:Zn is that the zinc forming ionic bonds with vacancy of phosphorous.
