• temperature of 750 °C, the ethylene (100 sccm) precursor gas flow was started and a small amount of the carrier gas was bubbled through a water bubbler in order to carry a defined amount of water vapor along with it. The amount of water vapor was monitored by using a commercial water vapour sensor built in
