Bi-layer Graphene (Image 1)

High-quality, bi-layered graphene on a copper substrate

Researchers at the University of California, Santa Barbara (UCSB), have successfully controlled the growth of high-quality, bi-layered graphene on a copper substrate using a method called chemical vapor deposition (CVD), which breaks down molecules of methane gas to build graphene sheets with carbon atoms. The discovery could pave the way for next-generation electronics application.

Kaustav Banerjee, a professor in the Electrical and Computer Engineering Department and director of the Nanoelectronics Research Lab at UCSB, led the research team that perfected the methods of growing the graphene sheets. Says Banerjee, "For the electronics industry to effectively use graphene, it must first be grown selectively and in larger sheets. We have developed a synthesis technique that yields high-quality and high-uniformity graphene that can be translated into a scalable process for industry applications."

The discovery turns graphene production into an industry-friendly process by improving the quality and uniformity of graphene using efficient and reproducible methods. The team was able to control the number of graphene layers produced--from mono-layer to bi-layer graphene--an important distinction for future applications in electronics and other technology.
