Example of Complex Plasma

Complex plasma does not only exists in laboratory. There are many examples of complex plasma that exists around us which you might not have noticed. For example, complex plasma occur naturally in planetary rings, comets, interstellar gas and noctilucent clouds in the upper atmosphere.

And there are also many applications in everyday life that is associated with complex plasma. For example, in microelectronics, we have dust contaminates from plasma etching in silicon wafer or in plasma processing which uses reactive gases. In fossil fuel MHD power generator. In solid fuel rocket exhausts. And also from electrode and wall erosion in Tokomak systems.
