Calculation of the composition of the equilibrium dusty plasma

Influence of emitting nanoparticles concentration to the density of free electron in the thermal dusty plasma

“…The buffer gas surrounding the particles is assumed to be neutral at all considered temperatures of the system. As a dust subsystem, we consider nanoparticles, which are balls of an n-type semiconductor [6,7], with particle radius R. Let us take the value of the charge inside a sphere with radius R as the charge of a dust particle. Then, under the condition that the buffer gas is not ionized for concentration of free electrons in the space between particles ned we get:…”

“…The presence of particles in thermal plasma leads to their charging. One of the key mechanisms of charge acquisition by nano and microparticles in a high temperature gas is thermionic emission [3][4][5][6][7][8][9][10][11][12]. The acquisition of an electric charge by nanoparticles due to the emission of electrons strongly affects the electrophysical properties of the system as a whole and the electrical conductivity in particular.…”

“…An alternative approach is the description method based on the "jelly" model for condensed particles. For micron particles in plasma, this model was first applied in [6][7][8][9]. The advantage of this model is that it can take into account the features of the internal structure of particles.…”
