Chemical analysis of H2/CH4 and H2/CH4/B2H6 high pressure-high power microwave plasma using TDLAS and OES techniques
Résumé
Microwave H2/CH4 and H2/CH4/B2H6 plasmas used for diamond deposition have been investigated by Infrared Tunable Diode Laser Absorption Spectroscopy (IR TDLAS) and Optical Emission Spectroscopy (OES) techniques in order to monitor six different molecular species CH4, C2H2, C2H4, C2H6, B2H6 and B.
