dc.description.abstract本論文中以低壓有機金屬化學汽相沉積法(LP-MOCVD)研製磷化銦鎵與砷化鎵異質結構,以作為金屬半導體場效電晶體(MESFET)之應用。研究內容包含成長磷化銦鎵及砷化鎵異質結構的磊晶層、對不同成長條件所得磊晶層的特性分析。 在成長磷化銦鎵與砷化鎵磊晶層時,調變五族與三族的比例以得到最佳的低應變晶格匹配結構。同時,利用雙晶x光繞射定量分析超晶格磊晶層。光激光半高寬分析也用來印證我們的磊晶結構的優越特性。為了得到較好的磷化銦鎵與砷化鎵超晶格結構,適當的五族氣體切換扮演著一重要角色。事實上,磷化銦鎵與砷化鎵間的異質接面品質嚴重地受到一”trade-off”切換條件所影響。藉由氣體切換的最佳化,可在磷化銦鎵與砷化鎵之間得到較平坦的界面。zh_TW
dc.description.abstractIn this thesis, we have fabricated a new InGaP/GaAs heterostructure grown by low-pressure metalorganic chemical vapor deposition (LP-MOCVD) for MESFET applications. The study includesd the epitaxial growth of the InGaP/GaAs heterostructure, structure and property characterization of epitaxial layers in different growth conditions. In the growth of InGaP and GaAs epi-layers, V/III-ratio was optimized to achieve the lattice-matched, strain free structure. Double crystal x-ray diffraction quantitatively studied the lattice mismatch of epitaxy. PL-FWHM data proved the superior properties of the epitaxial layer. To establish a better InGaP/GaAs heterostructure, the proper switching of group Ⅴ source (As and P) played a important role. The quality of the heterojunction between InGaP and GaAs was controlled carefully by a “trade-off” switching condition. Smooth interface between InGaP and GaAs was obtained due to the optimization of the switching conditions in this study.en_US
