GRAPHENE SYNTHESIS BY SUPPRESSING EVAPORATIVE SUBSTRATE LOSS DURING LOW PRESSURE CHEMICAL VAPOR DEPOSITION

摘要

Method for synthesizing large single-crystal graphene films by suppressing evaporative substrate loss in chemical vapor deposition, and graphene films synthesized thereby. The substrate may be configured as a tube prior to exposure to an organic compound at high temperature. Low flow rate of the gaseous carbon source may be employed, and this flow rate may be increased after an initial nucleation period.
