摘要：

The motion and distribution of charged dust grains under the action of electrostatic and gravitational forces near the boundary of a dusty plasma are investigated. It is shown that when gravity is negligible, a spatial localization of the dust can occur. For heavier grains, gravity enhances this localization, and causes a stratification of the dust density. For even heavier grains, the stratification disappears since the grains are pulled to the wall by gravity.
