摘要


本論文以化學氣相沉積系統製備直徑及電性皆可控制的矽奈米線,並以電場導向技術成功控制矽奈米線做規則的定向排列。藉由結合適當的高介電常數材料及外加應力,定向排列的矽奈米線在無接面場效電晶體,非揮發性記憶體,及生物分子感測器等元件的應用上展現無窮的潛力。此外,鍍碳的高掺雜n型矽奈米線做為鋰電池陽極材料也被證實能提供電池高能量密度及長時間使用壽命。

並列摘要


Well-aligned silicon nanowires with controlled diameter and doping concentration are successfully synthesized using the electric-field-assembly technology in a low pressure chemical vapor deposition system. By an appropriate combination of high-k dielectric and mechanical stress, aligned silicon nanowires show significant potential for applications in junctionless field-effect transistors, nonvolatile memories and biosensors. In addition, carbon-coated heavily-doped n-type SiNWs are demonstrated to be a promising lithium battery anode due to their high power density and long cycle life.
