“…A constant flow of 300 sccm hydrogen and 500 sccm argon was supplied during the whole process. Ethylene, introduced downstream of the carrier gases, was used as carbon feedstock and the flow rate was varied between 6 and 100 sccm (6,12,30,100 sccm). The gas was supplied via a 2m long Swagelok tube with an inner diameter of 3mm (internal volume 15 cm 3 ).…”

“…The carbon feedstock was introduced to the growth chamber only after a stable voltage drop across the heater was reached for a given current. The introduction of the hydrocarbon gas is accompanied by a noticeable jump in the voltage drop, indicating a higher resistivity and correspondingly greater heating power [12]. The working current through the heater was varied in the range 36-42 mA, which resulted in initial temperatures (immediately prior to hydrocarbon injection) from 630 °C to 690 °C.…”
