摘要

Field emission from a stand-alone carbon nanocoil has been investigated using a field-emission microscope. It was found that the emission spot consists of two parts: one is from the tip of the nanocoil and the other is from the side body of the top surface, which proves that the emission from a carbon nanocoil occurs not only at its tip, but also on its top surface where the electric field is concentrated. It was also confirmed that the structure of the carbon nanocoil changes during the field emission, which is considered to be induced by the Joule heating of the large emission current.
