  Study of Transport Process and Discharge Structure of Inductively Coupled Electronegative Plasmas Via Fluid Model and Analytic Theory Collaboration
  Author(s): Shu-Xia Zhao* and Yuan-He Sun
  
  The discharge structure of inductively coupled plasma is studied via fluid simulation and analytic theory collaboration. At low pressure, the discharge is stratified by the double layer, which is modelled as dipole moment. The parabolic profile is formed in the discharge core when recombination loss is negligible and both the electron and anions are the Boltzmann balanced. At increasing the pressure, the main characteristics, i.e., parabolic, elliptic and flat-topped profile, are experienced, predicted by the simulation and analytics. Self-coagulation is accompanied at all considered pressures. It is more a chemistry process and provides new means of constricting plasma. At its influence, electron density deviates from the Boltzmann equilibrium. For satisfying the neutrality of bulk plasma, the ambi-polar self-coagulation mechanism is suggested. At high pressure, the self-coagulation-.. Read More»
