Research in the Graves group focuses on the fundamentals and applications of weakly to partially ionized gases, or plasmas, to technological problems, primarily in the microelectronics industry. These plasmas operate at relatively low gas temperatures - around room temperature - and are therefore quite different from the hot, usually strongly magnetized plasmas in stars or that are used in thermonuclear fusion and weapons applications. The key problems in this field are related to the coupling of the chemically reactive neutral gas and electrons and ions that make up the plasma. This is especially true at surfaces exposed to the plasma. Indeed the primary applications of interest to the Graves group are related to interactions between the plasma and its bounding surfaces.
