Abstract:The void in the sheath of a radio-frequency(rf) dusty plasma is investigated experimentally. Dust particles in our experiment are created in situ using mixed reactive gases silane and ethane. Dust particles in radio frequency discharges form crystalline structure and display instabilities under certain conditions. The behaviour of the dust void as a function of rf power and gas pressure is studied.
