Graphene Platform started to offer large single-layer, single-crystal graphene samples. Graphene Platform offers these new sheets up to 10x10 mm in size, and they say it's the world's largest such material on offer.

These sheets have a defect-free, perfect six-membered rings structure and so offer high electron mobility and excellent optical, mechanical and thermal properties. The company offers these graphene sheets on Silicon Carbide (SiC).
