Formation of dusty plasma molecules

The electrostatic interaction of charged, dust-particle pairs in plasmas

“…Resendes et al [14], obtain the same result, as have we [16] and Riley [17]. Chen et al [6] use a simpler, more approximate method to calculate the energy, but arrive at a similar conclusion.…”

“…This is the procedure implied by Resendes et al [14] and Chen et al [6]. It is incorrect in this case, however, because the system is not isolated.…”

“…However, most are based on ion inertial effects [11][12][13] rather than a purely electrostatic mechanism as in molecular bonds. An exception is a model proposed by Resendes et al [14]. A similar model has also been proposed independently by Chen et al [6].…”

New Model of Dusty Plasma Particles Interaction

“…It clearly demonstrates the nonmonotonic behavior of the intergrain interaction which turns especially pronounced while increasing the grain number density or decreasing the screening parameter. The nonmonotonic behavior surely indicates that an attraction between grains turns possible for at least some values of plasma parameters which was also witnessed in [5]. The attraction mechanism remains the same as, e.g., for the molecule formation.…”

The effect of plasma shielding on dust particle interaction in low pressure plasmas

“…In many theoretical studies of dusty-plasma phase transitions, dust transport, two-body interactions, and dust-particle agglomeration, the charge on individual dust particles has been assumed constant during particle-particle interactions. [3][4][5][6] However, the charge on dust particles in a plasma can vary for many reasons. [7][8][9][10] One cause is the spatial variation in the electron velocity distribution function.…”
