AbstractThe basic features of the nonlinear waves, which are associated with positive ion dynamics and dust charge fluctuation, have been investigated by employing the reductive perturbation method in a dusty electronegative plasma containing Boltzmann electrons, vortex-like negative ions, mobile positive ions, and charge fluctuating stationary dust (negatively charged). It has been observed that the basic features of the nonlinear waves (viz. amplitude, width, speed, etc.) in the plasma system under consideration have been significantly modified by the trapping parameter (introduced for vortex-like distribution of negative ions). The implications of the results (obtained from this investigation) in space and laboratory experiments have been briefly discussed.

AbstractThe potential distribution around a charged dust grain in an electronegative plasma is obtained by using the appropriate dielectric susceptibilities for the Boltzmann distributed electrons and negative ions, and for the inertial positive ions that are streaming from the bulk plasma into the electronegative plasma sheath. The existence of oscillatory ion wakefields is shown. Positive ions are trapped/focused in the ion wakefields, and subsequently the negative dust particles are attracted to each other, forming ordered dust structures.

AbstractThrough a simple one-dimensional collisionless plasma sheath model, behavior of the floating potential in an electronegative plasma sheath is studied. Specially, the floating potential behavior as a function of the plasma electronegativity for various negative ion temperatures has been studied. It has been observed that negative ion temperature strongly affects the variation of floating potential.
