A particle-in-cell model is used to investigate the dust levitation phenomenon. A submicrometer-sized silicon dioxide particle lying on a silicon dioxide substrate is exposed to a low-energy electron beam and the flux of ions and electrons from a cold plasma. The combined effect of ion and electron accumulation between the particle and the substrate is reported. The results are of interest for dust mitigation in the semiconductor industry, the lunar exploration, and the explanation of the dust levitation.
