Influence of the Size Dependence of Work Function on the Concentration of Free Electrons in Thermal Dusty Plasma with Carbon Nanoparticles.

The influence of the size dependence of the work function of carbon nanoparticles on the concentration of free electrons in a thermal dusty plasma has been studied using an analytical model. It has been shown that there is a certain size of nanoparticles at which the most efficient emission of electrons from them into thermal plasma is achieved. The effect of temperature and volume fraction of nanoparticles on the nature of the dependence of the concentration of free electrons in a thermal dusty plasma on the radius of particles has been examined.
