Large amplitude double layers in dusty plasma with non-thermal electrons and two temperature isothermal ions

Formation of large amplitude double layers in a dusty plasma whose constituents are warm dust grains, non-thermal electrons and two-temperature isothermal ions are studied using Sagdeev's pseudopotential technique. Existence of double layers are investigated. It is found that the temperature of the dust particles, non-thermal electrons and ion-temperature all play significant role in determining the region of the existence of double layers.
