A Comparative Study of Electron Transport Coefficients in the Pristine and Dusty Argon Plasma

A simple self-consistent kinetic model for electrons is presented. This model is based on the solution of Boltzmann transport equation for electron energy distribution function and values of electron transport coefficients such as drift velocity, mean electron energy, diffusion coefficient, mobility and ionization coefficient, determined numerically in pristine and dusty direct current argon glow discharge. Orbital motion limited model used in calculating dust particle surface potential. Differences in dynamics of electrons are calculated the reduced electric field in the range of 30–200 Td. Results show that the dust in the plasma decreases electron temperature, mean electron energy, ionization coefficient and increases other. Also the influence of dust particle in low reduced electric field strength region is found to be larger than in high reduced electric field strength region.
