Graphene Size Raised and Synthesis Time Dramatically Reduced

A Korean company, Haesung DS, has developed a method to mass-produce single-crystal graphene, with a wafer size over 30″ and uniform characteristics. As well as producing a large wafer, the company also reduced synthesis time to 17 minutes. Until recently, a sheet of graphene took between three and four hours to synthesise. Synthetic equipment was developed with another company, PNS; the equipment can synthesise four sheets at once using chemical vapour deposition and rapid thermal annealing.
