Abstract
Field emission properties of standalone carbon nanotubes have been investigated in terms of the capped and open-ended tip shapes. The capped multiwall nanotube with a tip curvature of ∼2.5 nm is compared with the open-ended single wall nanotube with a diameter of ∼5 nm. These samples have almost the same current-voltage characteristics but show different field-emission-microscope images. The capped one shows some bright spots and in contrast the open-ended one shows twelve bright stripes with a spindle shape. The magnification of the images is larger for the capped one than for the open-ended one.
