摘要: Bohm criterion for dust-electron plasmas induced by UV irradiation is investigated Sagdeev potential, taking into account the self-consistent dust charge variation. In collisionless limit, Boltzmann electron distribution and cold fluid in sheath are adopted. It found that velocity decreases with increasing density bulk plasma. The results examined to be reliable quantitative analysis of potential.
