Chinese Abstract

使用AFM和STM研究了鈦酸納米管。得到了納米管表面的精細結構。在納米管表面觀察到一個約0.8nm高的大臺階,這是由於納米管的螺旋特性造成的。還觀察到表面各處有楞邊平行於管軸的小臺階。這些小臺階與鈦酸片層上的相同,是Ti-O八面體的連接方式造成。這些結果與先前在TEM研究基礎上提出的鈦酸納米管模型相符合。

English Abstract

AFM and STM are used to study the trititanate nanotubes. Detailed surface information is achieved. One large step with height about 0.8 nm is observed on the surface of the nanotubes, this step is formed due to the scroll nature of the tube. Small steps all around the surface are also observed with their edge parallel to the tube axis. These small steps are the same as that on the trititanate layers and are formed due to the connecting way of the Ti-O octahedrals. These results agree well with the trititanate nanotube model proposed previously based on TEM study.
