Building larger graphene-hBN sheets with molecular beam epitaxy
A University of Michigan research team has developed the first reliable, scalable method for growing single layers of hexagonal boron nitride (hBN) on graphene. The approach can produce large sheets of high-quality hBN with the widely used molecular-beam epitaxy process.
Graphene-hBN structures could be used to efficiently power LEDs that generate deep-UV light for lasers and air purifiers and could also be used for quantum computing devices.
This project was led at U-M by Zetian Mi, a professor of electrical engineering and computer science, and Ping Wang, a postdoctoral researcher in electrical engineering and computer science, with collaborators from a range of disciplines at U-M, Ohio State University, Yale University, and UES, Inc.
