摘要

本論文研究主要目的在於了解一維二六族半導體奈米材料的成長機制進而控制其製造與形成。特別地，本論文還檢測了二六族半導體材料的一維結構和不同形貌在奈米尺度下所導致之新奇特性。
我們還試著了解巨觀的實驗裝置改變如何影響奈米材料在微觀上的變化，更近一步了解與控制一維奈米材料的成長，可以使我們能更容易控制奈米材料的結構與形貌，並更容易操作使其成為有用的奈米元件。
本論文涵蓋了下列材料的合成與特性分析: (1)氧化鋅奈米樹枝與奈米塔 (2)硒化鋅奈米線 (3)氧化鋅奈米瓶與奈米針尖複合物 (4)金屬鋅和錫的奈米管與金屬銅和銀的奈米管/奈米線之接合 (5)氧化鋅奈米管。

Motivated by a desire to understand the basic concepts of one-dimensional nanostructure growth, the research described in this thesis aims at understanding the basic mechanisms controlling the synthesis and formation of a specific group of II-VI semiconducting nanostructures. In particular, this thesis examines one-dimensional nanostructures and different morphologies of semiconductors that lead to the novel properties of the materials at the nanoscale.
In order to understand how to manipulate the properties of the grown nanostructures, this thesis focuses on having an understanding of the growth mechanism that dictates the morphology and structure. In addition, we also try to understand the impact changes on the nanoscopic scale of the nanomaterials due to the macroscopic setup in the experiment. Having a better understanding and exerting more precise control over the growth of nanomaterials will allow a higher level of selectivity, more control over dimensionality and the type of morphology, easier manipulation, and the simpler incorporation of these structures into a nanotechnological device.
In general, this thesis covers the synthesis and characterization of the following nanomaterials: (1) ZnO nanodendrites and nanotowers, (2) ZnSe nanowires, (3) ZnO nanobottles decorated with ZnO nanotips, (4) metal (Zn, Sn) nanotubes and metal (Cu, Ag) nanotube/nanowire junctions, and (5) ZnO nanotubes. Efforts have been made to pinpoint the underlying science and to exploit their possible engineering applications.
