Abstract
The aim of this brief report is to study the behaviour of sheath structure in a multicomponent plasma with dust-neutral collisions. The plasma consist s of electrons, ions, micron size negatively charged dust particles and neu trals. The sheath-edge potential and sheath width are calculated for collis ionally dominated sheath. Comparison of collisionless and collisionally dom inated sheath are made.
