Ionization Balance in Low-Temperature Plasmas with Nanosized Dust

Ionization mechanisms in the low-temperature thermal plasma, which contains alkali metal atoms as ionizable component and nanosized dust grains, are studied. In such a electrons captured by because work function of grains depends on their sizes, electron adsorption rate is more than thermionic emission for grains. Accordingly, an increase grain number leads to decrease volume ionization recombination rates, they depend density electrons. At same time, role surface processes plasma balance increased, total increased. The approximate calculation techniques low high densities proposed. criterions calculations specified.
