| Abstract | A single-walled carbon nanotube (SWNT) is a nanoscale cylinder composed of one single-layer sheet of carbon atoms. As-grown SWNTs by chemical vapor deposition have a cap at one end and a catalyst particle at the other end. In the application of SWNT to scanning tunneling microscopy tip [1], electron source [2], etc., the SWNT cap structure needs evaluation for precise control. Furthermore, it is important to observe the cap structure to reveal the SWNT growth mechanism. Although field emission microscopy (FEM) images of SWNT caps have been studied by Dean et al. [3], no systematic relationships between field electron emission (FE) images and cap structures were found. So far, FE from a structure defined SWNT has not been explored yet because of the difficulty in the sample treatment [2]. We need a series of observations of the same SWNT by scanning electron microscopy (SEM), FEM and transmission electron microscopy (TEM) to understand the relationship between FEM images and the SWNT cap structure. |
