摘要：
We have measured the size of the localized electron emission sites on multiwalled carbon nanotubes (MWNTs) with caps closed by a fullerenelike structure. MWNTs were individually mounted on tungsten support tips and imaged with a field emission microscope (FEM). The magnification of the FEM was calibrated using electron ray tracing and verified by comparing transmission electron microscope images. The FEM image was also tested for effects of the lateral energy spread. We found ring-shaped emission areas with three flattened sides, of a radius of 1.7 +/- 0.3 nm, and separated by 5 +/- 1 nm.
