Texas Instruments (TI) is researching Graphene-growing for quite a while, and have recently demonstrated growing large-grain graphene crystals (up to 0.5 millimeter diameter) using low-pressure chemical vapor deposition inside copper-foil enclosures (and they are investigating growth on other substrates, more stable then copper). TI says that the new method allows them to grow graphene that is 30 times larger than before.

This research is conducted in collaboration with IBM's T.J. Watson Research Center, the Nanoelectronic Research Initiative (NRI), and the University of Texas.
