CVD Graphene sheets have been deposited onto 50 micron thick Cu foils using modified chemical vapor technique. In our method, we have paid close attention to engineering defect density and single domain sizes. Most CVD graphene chambers produce small (100nm - 1um) graphene sheets. Our process parameters have been optimized to reduce the point defect (vacancy) concentration, improve crystallinity, increase single domain size, and reduce 1D grain boundary defect density. Our CVD graphene products undergo weekly routine quality control tests to ensure the growth system is accurate and parameters are up to date. Our CVD graphene on copper foils measure 2 inches x 2 inches (~5 x5 cm in size).
