Alignments of a Microparticle Pair in a Glow Discharge
Molecules, 2021 Stability of a vertically aligned microparticle pair in a stratified glow DC discharge is experimentally investigated. Using laser perturbations, it is shown that, for the same discharge parameters, a pair of microparticles can be suspended in two stable
