Local electric field at the emitting surface of a carbon nanotube
GC Kokkorakis, A Modinos, JP Xanthakis - Journal of applied physics, 2002 - pubs.aip.org
We present a method for the calculation of the local electric field at the surface of a
nanoscopic emitting structure. The method is here applied to carbon nanotubes (NT) where
symmetry makes the application of the method easier. The NT is simulated as a cylindrical
array of touching spheres, each sphere representing an atom of the tube. The electrostatic
potential is written as a linear combination of the potentials produced by each of the
spheres. We calculate the local electric field and the corresponding enhancement factor γ for …
