CVD Graphene Films

CVD Graphene Films are known to have the highest quality. There are other methods of making graphene films however they typically have grain boundary problems. The CVD graphene films produce a homogeneous films without grain boundary issues.

What is Graphene?

Graphene is a one atom thick sheet or film of carbon atoms. It is strong yet low weight and it conducts heat and electricity. In fact, graphene is the most thermally conductive material known to man. Scientists had theorized about graphene for decades before it was successfully synthesized in the lab in 2004 by Geim et al. It is two-dimensional, it interacts favorably with light and with other materials.  Graphene is a highly crystalline carbon sheet. Carbon atoms are densely packed in a regular hexagonal sp2 bonded structure. It can best be envisioned as a one-atom thick layer of graphite. CVD graphene films are the building block for graphene based electronic and photonic devices.

CVD Graphene Transfer

CVD graphene transfer is available for substrates such as PET that can’t withstand the CVD Graphene Synthesis processing temperatures.  The CVD Graphene film can be transferred to other substrates by a variety of methods such as using solvents to release the film from the substrate in a liquid medium and floating it onto a different substrate.

CVD Graphene Films Quality control

All our CVD Graphene Films are subjected to a rigorous quality control in order to ensure a high quality and reproducibility of the graphene. CVD graphene films quality control methods are;

Raman Spectroscopy: I(G)/I(2D)<0.5; I(D)/I(G)<0.05

Optical Microscopy inspection of each individual sample to ensure good transfer quality and purity

If your application requires more specific controls (AFM, SEM…) please do not hesitate to contact us.
