Cobalt (0001) A Co (0001) film is first grown on a wolfram (110) substrate, following which chemical vapor deposition of propylene at 450 °C enables graphene growth on Co (0001). This results in a p (1x1) structure along with structures that indicated domains of graphene slightly rotated with respect to the Co lattice.

Harper's pusher furnaces and tunnel kilns are ideal for processes requiring precise control of temperature and atmosphere, for those with longer residence times that require exact control of the heat up rate of the product (temperature profile), and those with a lower gas/solid reaction.
High-temperature furnace for SiC and GaN annealing and Graphene growth. The unique design of the centrotherm metal-free heating allows process temperatures up to 2000 °C and shorter process cycle times. c.ACTIVATOR 150 allows a cost-effective production due to its small footprint and low cost of ownership.

Equipment Description The CVD FirstNano Graphene furnace is currently configured for graphene on Cu foil, graphene sublimation from SiC samples (epitaxial graphene), and H2 etch clean of samples. Samples are heated via 10kW RF induction heating.
monolayer PMMA derived graphene (PG) was: (1) evacuate a standard 1-inch quartz tube furnace to 100 mTorr and maintain the temperature at 1000 ºC; (2) introduce the PMMA/Cu film into the furnace with the H. 2 (50 sccm) and Ar (500 sccm) flow for 10-20 min, maintaining the
System Features. Temperature Controller: PID temperature controller with K type thermocouple.
The 3D Ni nanowire foam was then heated to within a temperature range of 500–1000 °C in a tube furnace with H 2 (50 sccm), Ar (300 sccm) and CH 4 (50 sccm) gas flowing for the growth time of 90 min, allowing for sufficient dissolution of the carbon sources and for the graphene to fully develop on the Ni catalyst.
Also, graphene growth using CVD requires sequential heating in an inert or reducing atmosphere followed by hydrocarbon exposure, and substrate handling and the transitions between zones must consider this requirement 22.

For graphene growth using LPCVD, the Cu foil was placed inside the furnace tube and it was evacuated up to 1 × 10 −1 Pa/0.75 mTorr using attached vacuum pump, to remove the contaminations (moisture, dust, oxygen and other atmospheric gases) that can affect the graphene quality.
We have successfully developed a CVD furnace that allows in situ study of the quality, structure and size of graphene flakes during growth. The substrate heater allows for temperatures exceeding 1500 °C, which enables observations on the CVD growth of graphene on liquid copper.
