Modeling of diamond growth from a microwave plasma: C 2 H as growth species

Hans Rau; Friederike Picht

Diamond growth experiments were performed in a microwave plasma ball reactor on silicon wafers or on a molybdenum sheet provided with cones. All substrates had been treated by scratching with diamond powder in advance. The gas mixture used was CH 4 /H 2 , sometimes with the addition of CO. Substrate temperatures ranged from 953 to 1428 K, pressures from 100 to 400 mbar, and microwave powers from 250 to 700 W. A strong preference of diamond growth was observed on the cones in the molybdenum substrate
