Great article. IMO, CVD is the most promising scalable, manufacturing method, but the following advances have to happen:
- Able to grow Graphene of arbitrary thickness on a wide variety of surfaces
- Achieving CVD at low temperature
- Control of grain size, ripples, doping level, and number of layers
- Coming up with a cost-effective way to handle to the Transfer step, or eliminating it entirely
As the current market for graphene applications is driven by the production of this material, there is a clear hierarchy in how soon the applications will reach the user or consumer. Those that use the lowest- grade, cheapest and most available material will be the first to appear, probably in a few years, and those which require the highest, electronic- quality grades or biocompatibility may well take decades to develop.Also, because developments in the last few years were extremely rapid,graphene’s prospects continue to improve.
- bsder 12y agoI'm surprised that they seem to be concentrating so little on CVD. Yes, CVD is expensive, but it's not rocket science anymore. We can do all manner of things to pizza-sized wafers of silicon in CVD. Shining lasers just above the surface to heat the gas but not the substrate is one of the easiest ones. It feels like the labs are all chasing patents rather than actually doing research.
- matthewmcg 12y agoPerhaps I am misunderstanding the terminology, but isn't graphene always the same thickness, i.e. one atomic layer?
