Abstract
In this communication the authors have derived an almost exact expression for the tunneling probability of an electron through the surface potential barrier on account of a negative charge on a cylindrical metallic dust particle and have used it to obtain the field emission current density from the surface of the particle. Based on these results, a parametric analysis of the phenomenon and comparison to the results of JWKB approximation (similar to Fowler–Nordheim theory) has been presented. These results are also applicable to a number of applications based on electric field emission from a thin metallic wire surrounded by a coaxial cylindrical surface at a high electric potential with respect to the wire. The investigation is of relevance to dusty plasmas in space and laboratory and carbon nanotubes.
