goals

The student will develop a physical understanding of the plasma boundary sheath and an overview on their role in plasma technology.

content

The formation of electron depleted boundary sheaths is a universal plasma phenomenon. Sheaths form wherever a plasma is bounded by a material surface (wall, electrode, substrate). The sheath determines to a great extent the physical and technical properties of the plasma and its energetic communication with the outside world.

  • Formation of a plasma boundary sheath
  • Stationary boundary sheaths
  • Radio frequency driven sheaths
  • Boundary sheath models
  • Technological implications
