Behavior of the floating potential in an electronegative sheath as a function of electronegativity and negative ion temperature

Abstract

AbstractThrough a simple one-dimensional collisionless plasma sheath model, behavior of the floating potential in an electronegative plasma sheath is studied. Specially, the floating potential behavior as a function of the plasma electronegativity for various negative ion temperatures has been studied. It has been observed that negative ion temperature strongly affects the variation of floating potential.
