Abstract: | A dusty plasma system consisting of electrons, ions, and negative as well as positive dust particles has been considered. The basic properties of arbitrary amplitude solitary potential structures that may exist in such a multi-component dusty plasma have been theoretically investigated by the pseudo-potential approach. It has been found that the presence of additional positive dust component does not only significantly modify the basic properties of solitary potential structures, but also causes the coexistence of positive and negative solitary potential structures, which is a completely new feature shown in a dusty plasma with dust of opposite polarity. |
