A constant mean free path collisional plasma sheath model is investigated in the presence of two-temperature q-nonextensive electrons and fluid ions. By using Sagdeev potential technique, a modified Bohm sheath criterion is derived and also verified.

Plasma characteristics in the gap at lowered pressure in the presence of primary electrons are analyzed for the hydrodynamic model in the cold ion approximation. It is demonstrated that at a certain critical ionization level, the plasma state changes
