摘要

在二維平面上形成金屬奈米粒子陳列的方法在最近奈米科技的發展中愈形重要，其用途包括奈米觸媒、化學和生物檢測及奈米光子學（表面電漿子）等。在本文中我們介紹一些相關的物理與化學的製備方法及顯微檢測技術，其中物理製備方法方面，會簡介最近發現的鐵、鈷、鎳奈米原子團簇(nanocluster)之量子成核機制，而在化學製備方法將介紹如何利用有機矽烷(organosilane)自組裝單分子層(self-assembled monolayer, SAM)作為連接層而能將金奈米粒子從單分散金溶膠(monodispersed gold sol)中吸附到分子層上以形成穩定結合的金奈米粒子／分子膜／基板複合結構。

Formation of two-dimensional metal nanoparticle arrays on technologically relevant substrates is gaining more interest in nanotechnology due to its applications in nanocatalyst, chemical and biological sensing, and nanophotonics (plasmonics). In this article, we introduce physical and chemical routes to synthesize such nanoparticles on two-dimensional planes. We will introduce the new concept of quantum nucleation mechanism in the traditional method of physical vapor deposition. Moreover, we will show how to prepare such particles on substrates from monodispersed gold colloidal solutions using linking organosilane self-assembled monolayers (SAMs). In addition, we will show some representative microscopic studies of such arrays.
