Cambridge spin-out starts producing graphene at commercial scale

Paragraf is producing graphene ‘wafers’ and graphene-based electronic devices, which could be used in transistors, where graphene-based chips could deliver speeds more than ten times faster than silicon chips; and in chemical and electrical sensors, where graphene could increase sensitivity by a factor of more than 30. Professor Sir Colin Humphreys from the Centre for Gallium Nitride in Cambridge’s Department of Materials Science and Metallurgy, along with his former postdoctoral researchers Dr Simon Thomas and Dr Ivor Guiney, developed a new way to make large-area graphene in 2015. Using their method, the researchers were able form high-quality graphene wafers up to eight inches in diameter, beating not only other university research groups worldwide, but also companies like IBM, Intel and Samsung.
