| Research |
Dr. Grotjohn's scholarly interests include the modeling, design, diagnostics, and control of plasma-assisted materials processes and processing machines. This work focuses on the use of models, including electromagnetic, plasma dynamic, and plasma chemistry models, for the design and control of microwave plasma reactors used for materials processing. Specific processes studied have included diamond CVD deposition, amorphous carbon deposition, semiconductor etching, and general microwave-generated plasma discharges operated as ion and radical sources. In coordination with the modeling studies are plasma diagnostic studies including a variety of techniques including optical emission spectroscopy, laser spectroscopy, Langmuir probes, and millimeter wave resonator diagnostics. Recent work is especially looking at mini- and micro-scale plasma discharges and their application. |
