Here, the finite value of ion-neutral collisions, the temperature of negative and positive ions, the mass of negative ions, and negative ion density have been considered to uncover the realistic situation. We have considered CF4 electronegative plasma where CF3+ and F- are the dominant charged species formed. The influence of electronegativity and positive ion temperature on positive ion velocity, positive ion density, electric potential, and net space charge density have been analysed to uncover the realistic situation. The plasma sheath profile has been investigated for the very first time using this combination of charged species distribution.}, number={4}, journal={Journal of Theoretical and Applied Physics}, publisher={OICC Press}, author={Dhawan, Rajat and Sarika and Sehrawat, Rajeev and Mittal, Rashmi and Choudhary, Ishan}, year={2024}, month={Aug.}, keywords={Electronegative plasma, Plasma sheath, Plasma surface interaction, Non-extensive statistics, Constant mean free path, Fluid behaviour} }
