Graphene Cost – Material vs CVD Instrument
When people ask about about graphene cost, it can mean two different things. One- how much does a sheet of graphene cost to buy, or two-how much does it cost to produce a sheet of graphene. Micro Photonics is able to provide you with both graphene material on different substrates and CVD instruments to produce your own high quality graphene. We discuss each possibility below.
The cost to purchase graphene material
Micro Photonics supplies graphene on different substrates (copper, PET, Silicon, Glass) and in different sizes. The sizes can range from 10×10 mm up to a sheet that has a 30″ diagonal, or a 6″ wide sheet that is 3 meters long. We can also arrange to have your graphene put onto your specific substrate. Call us for more information (610) 366-7103. There are several sources for graphene. Your application will determine the level of quality you need, which will determine which partner you should choose.
The cost to produce the sheets in your lab
The total cost of graphene manufacturing includes; instrument, graphene synthesis, and transfer
Graphene Instrument Considerations
The size of the film you need, its quality, automation and the ability to make 2D materials will determine which instrument you will need and the cost of that instrument. You can add larger chamber sizes for larger sheets, more gases, and solid sources for more complex films, and multiple chambers to name a few options which will affect the end price of the instrument.
The cost of production depends on the synthesis technology and can be estimated based on the price of carbon precursors Methane and Ar gases for CVD, or graphite for other techniques. Substrate material will also be needed. For CVD growth, copper is typically used for growth. It offers good thermal stability and good structure of crystal growth. Micro Photonics can supply you with copper or we can recommend the quality of copper to purchase. We can help you find local suppliers of gas bottles.
The transfer process can either be wet or dry and will have different costs associated with it as well. Micro Photonics offers transfer kits with thermal films or we can advise you on how to use wet chemistry to transfer you films. You can visit the graphene transfer page for more information on transferring films.
We would be happy to help you in your search for high quality graphene material and instrumentation.
