Analytical solution to the Langmuir spherical problem
arXiv:1008.4935
Abstract
The current paper discusses and analytically solves the Langmuir spherical problem. A general solution has been obtained in a parametric representation and expressed in terms of the Airy function. A solution to the electric potential in a spherical vacuum diode with limited electron flow has also been reached.
