First results from Liquid Metal Catalist CVD Reactor:
operando investigation of Graphene growth on liquid copper
We designed a CVD reactor for in situ observations of the growth of 2D materials on very hot substrates. Experimental methods include simultaneous operando synchrotron X-ray scattering, Raman spectroscopy, and optical microscopy techniques. This CVD furnace is a very effective tool to investigate the key parameters that affect the growth of 2D materials.
2D materials such as graphene, hexagonal boron nitride, silicene and others, are currently amongst the most intensively studied classes of materials that hold great promise for future applications in many technological areas. However, the main hurdle against practical utilization of 2DMs is the lack of effective mass production techniques to satisfy the growing qualitative and quantitative demands for scientific and technological applications.
It is known that formation of defects is prevented by having good control over both the growth conditions and substrate quality. For instance, high-quality graphene can be grown on copper substrates in the molten phase from methane at high temperatures. However, because of the very harsh conditions during synthesis of graphene on liquid copper, only ex situ studies have been reported until now, after the copper has been solidified, possibly affecting the graphene layer that is adhering to it. 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.
