Dust cloud evolution in sub-stellar atmospheres via plasma deposition and plasma sputtering [PDF]

, 2017
Context. In contemporary sub-stellar model atmospheres, dust growth occurs through neutral gas-phase surface chemistry. Recently, there has been a growing body of theoretical and observational evidence suggesting that ionisation processes can also occur.
