Au（111）取向膜的制备与结构表征

在羊晶硅Ｓｉ（１１１）上，通过电子束蒸发沉积方法制备Ａｕ（１１１）取向膜，用扫描电子显微镜（ＳＥＭ）、Ｘ－射线光电子能谱（ＸＰＳ）和原子力显微镜（ＡＦＭ）分析在征Ａｕ（１１１）膜的表面微结构和表面晶格取向的原子图像。实验结果表明，在超高真空的条件下，控制优化实验条件能制备高度取向的Ａｕ（１１１）膜，这在分子自组装技术中起着关键作用，在纳米薄膜材料科学中具有重要意义。

Preparation and Structure Characterization of Au(111)Oriented Film

Au(111) oriented film is prepared by electron-beam evaporation deposition on single crystal Si(111).Surface microstructure and atomic images of surface lattice orientation of Au (111) film are characterized by scanning electron microscope,X-ray photoelectron sperctrometer and atomic force microscope.experimental results suggest that oriented Au (111)film can be prepared by controlling better experimental procedure at ultra-high vacuum condition ,which play a key part in a molecular self-assembly technique and have important significance in nanometer thin film materials science.
