Generalized Bohm Criterion for Electronegative Complex Plasma

In this work, we have generalized the computation of Bohm criterion for electronegative complex plasma. For this, we have established a one‐dimensional, unmagnetized and stationary theoretical model where the positive ions and dust particles are modeled by fluid equations. The electrons and negative ions are considered in thermodynamic equilibrium; therefore they obey to Boltzmann's statistic. In this case, the numerical results show that the generalized Bohm velocity is small compared to the classical value. For electronegative dusty plasma, the corrections are less important.
