Epitaxial graphene may transform the computing and communications industry.
Ultrafast THz dynamics of Epitaxial graphene Interlayer energy transfer in Epitaxial graphene
Multilayer epitaxial graphene (MEG) was first reported about a decade ago, but it has already revealed a wealth of new physics and is also envisioned to find a truly extensive range of applications in science and engineering. In particular, MEG holds considerable promise to succeed current semiconducting materials for ultrahigh-speed high-performance nanoelectronics and nanophotonics applications. We have performed experiments using ultrafast optical methods to study the high-speed (terahertz) properties of MEG. Specifically, we have observed for the first time how electrons in one layer can interact with electrons in another layer; this may open up new approaches to managing heat flow in nanoelectronic devices.
