Abstract
The characteristics of one-dimensional electron diode with low-pressure argon scattering gas are analyzed by a Monte Carlo method. Experimentally determined differential elastic scattering cross sections, extra-polated to zero energy, are employed. Current-voltage characteristics are compared with those obtained from a hard-sphere collision model. Negative resistance is found for low emission current densities and low pressure as a result of the Ramsauer cross section. The randomization of energy between velocity components is found to be quite large for accelerating potentials and pressure-electrode separation values as low as ½ Torr·cm. The energy dependence of total cross section has a more pronounced effect on the current-voltage curves than nonisotropic scattering.
