Beyond Van der Waals Graphene-metal interactions | Haozhe Wang
Summary :
With extraordinary properties, graphene has been applied in various studies to explore new phenomena, new understandings, and new applications. With only one atomic layer thick and all its atoms are on the surface, graphene’s properties could be altered by being brought into contact with any arbitrary surfaces, and similarly the close presence of graphene contact could change the properties of that surface as well. Our research aims to provide insights into graphene-metal interactions by analyze novel phenomena and develop practical applications. First, we modified the graphene-copper interface to prevent the growths of thicker graphene islands in order to grow a uniform bilayer graphene (2LG), by introducing the concept of interface adhesive energy. To characterize the different types of 2LG better, we developed a machine-learning-assisted Raman analysis tool and confirmed that our FMmode- grown 2LG is of quasi-AB-stacking.
