Graphene synthesis by chemical vapor deposition (CVD) was first reported more than a decade ago. Since then, the number of publications on graphene synthesis is growing exponentially to reach more than 12,000 articles per year in 2019. Currently, high quality graphene having low-defect density, large grain size and controlled number of layers is produced using engineered metal catalyst under strictly controlled conditions in research laboratories. This lecture covers the development from the last decade covering these topics:
- (1) synthesis mechanism;
- (2) CVD systems;
- (3) Adsorption versus absorption driven growth;
- (4) Thermodynamics of catalyst-carbon system;
- (5) Controlling graphene uniformity, growth rate and domain alignment;
- (6) Introduction to the Gr-ResQ* project at Illinois;
- (7) Overview of the nanoHUB tools suite related to the Gr-ResQ project.
Overall, these two lectures are meant to be a general introduction on the opportunities and challenges related to graphene synthesis.
This is part one of a two part lecture, part one is available here.
