Abstract: 本計畫一年來 陳家俊 、林麗瓊、吳季珍、王崇人分別在Sb/sub 2/S/sub 3/、InN、GaN、ZnO、TiO/sub 2/、Ga/sub 2/O/sub 3/、Au等一維奈米材料的製備與特殊功能研究上有具體進展,除了有效製備各種奈米管、奈米線之外,我們更進一步研究其功能性的應用,以及特殊設計模式成長成為可行,有效促進下游的功能性應用研究。在光電特性分析上,彭維鋒利用同步輻射中心的X光吸收光譜(XANES)結合林麗瓊的電子束螢光光譜儀(Cathodoluminescence; CL),以及可以對奈米大小尺寸的材料的電子結構,形貌、成分、螢光特性做有效分析。同時,UV Micro-Raman/PL系統在加裝325-nm光源之後,可以在有效再低溫下測量寬能距材料螢光與拉曼光譜,對本計畫光電特性的研究有極大幫助。在功能性應用方面,王崇人將研發出來的金奈米柱的表面電漿波應用於生物分子檢測,並且發展出光奈米光熱轉換的方法,可應用於生物晶片檢測及醫療聲波顯像上。陳啟東利用e-beam writer連結CNT並測其電性,在MWCNT上看到Columb oscillation。同時,呂宗昕與莊敏宏分別將CNT應用在鋰電池電極與場發射方面的研究,初步測 量顯示鋰電池充電量遠出過當前的文獻報告。呂宗昕也發展奈米結構鋰電池陽極材料,這配合奈米碳管鋰電池應用將有極大潛力。
In the past year the synthesis of 1-dimensional materials of Sb/sub 2/S/sub 3/、InN、GaN、ZnO、TiO/sub 2/、Ga/sub 2/O/sub 3/ and Au has been improved significantly by C.C. Chen, L.C. Chen, J.J. Wu, and C.R.C. Wang. Besides the successful preparation nanotubes, nanowires nanorods and nanocables, special control of the growth and targeted functionality of the materials have been realized. Potential applications in sensors and biochips are also addressed. W.F. Pong utilized XANES at SRRC to study the electronic structures of our nanomaterials, while L.C. Chen applied FE-SEM equipped with EDS and cathodoluminescence (CL) to achieve nm-resolution of the morphology,composition, and optical property of the nanomaterials. Meanwhile, the UV Micro-Raman/PL system equipped with the new 325-nm laser allows effective investigation of wide bandgap materials. In functionalization and applications, C.R.C. Wang successfully applied surface plasmon resonance to the Au-nanorods for selective sensing of biomolecules. A newly developed optothermal conversion technique has been developed. C.T. Chen has successfully applied his e-beam writer-based technique to study the transport properties of carbon nanotubes. Clear Coulomb oscillation has been demonstrated in one of the multiwall carbon nanotubes. C.H. Lu and M.H. Chuang have make progresses in the lithium battery electrode and field emission, respectively, utilizing the CNTs produced in this project. The charge capacitance of our samples exceed those reported in the literature.C.H. Lu also developed a nano-structured anode material for the lithium battery, which is highly desirable for the next generation battery.
