The study of the properties of boundaries between different materials—something that could one day change the world of electronics—is getting a boost from research being done by scientists in UT’s College of Engineering and Oak Ridge National Laboratory.

Gong Gu, an associate professor in the Department of Electrical Engineering and Computer Science, initiated a research effort to seamlessly join two two-dimensional crystals, earning a spot in the journal Science earlier this year.

“When you grow typical three-dimensional crystals on top of one another, the interface where they meet is, by default, two-dimensional,” said Gu. “That process is called heteroepitaxy. We’ve taken that a step further by joining a pair of two-dimensional crystals, which makes that boundary where they meet one-dimensional.”
