WebErickson et al. (1996) tried to detect CH absorption in a microwave CVD reactor using CH4 diluted in H2 as the feed gas. They were unable to detect the CH absorption. Using the detection limit of their system, they placed an upper limit of 10 cm on the CH density. From this and their measured CH3 density, they placed an upper bound on the hydrogen … Web25 jul. 2016 · In CVD synthesis, microwaves split apart the hydrocarbon molecules fed into the reactor (left). These fragments migrate down to the colder diamond seed and attach to the growing diamond surface. The synthetic diamond grows in thin layers, and its final thickness depends on the amount of time allowed for growth.
