Sheath formation in the presence of non-extensive electron distribution

The main aim of this article is to recognize the sheath formation in the presence of non-extensive electron distribution. The role of ion–neutral collision parameter K and the non-extensive parameter “q” has been discussed. Existing literature suggests that the presence of non-extensive electrons potentially modifies the plasma sheath behaviour. However, numerical calculations over the full plasma range, jointly addressing the sheath and presheath, are rare. Sheath formation, being a very fundamental phenomenon, deserves enough investigation in the region of non-extensive distribution of particles. This study attempts to bridge the gap in understanding the formation of the sheath in collisional plasma in the light of both Boltzmann and q-distributed non-extensive electrons.
