Dusty sheaths in plasmas with two-temperature electrons

Self-consistent dusty sheaths are investigated by using computer simulations of a temporal evolution of one-dimensional slab plasma with two-temperature electrons and dust particles. The evolution is caused by a collection of electrons and ions by both an electrode (wall) and dust particles, which are initially immersed into plasma. The peculiarity of the sheaths is non-monotonic spatial distributions of an electric potential that causes a protection of the electrode (wall) from fast ions. The protection is depending on rations of both electron temperatures and densities
