Abstract

The work functions of semiconducting and metallic single-walled carbon nanotubes were calculated by use of the first-principle cluster method. A series of metallic and semiconducting carbon nanotube clusters, containing 15-layer (metallic) or 16-layer (semiconducting) atoms in each cluster, with the practical diameter (1.0-2.0 nm), were adopted. It was found that the calculated workfunctions of carbon nanotubes were close to the experimental value, and were less sensitive to the tube diameter and conductivity.
