There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Professor De Heer will be speaking on the topic of The Future is Paved in Epigraphene. The talk will discuss how Graphene has been widely advertised as the new wonder material that can be produced by exfoliating graphite, using Scotch tape, down to a sheet that is one atom thick. Because it is a 2-dimensional material, it was expected to revolutionize electronics, but 15 years of exfoliated graphene research has failed to even remotely meet this challenge. Starting in 2000, the Georgia Tech epigraphene electronics group has taken a different approach to graphene-based nanoelectronics, by growing it on single crystals of silicon carbide, using a method that was known for more than 50 years. This form of graphene, called epigraphene, has not only shown a wide variety of important new properties, it also is intrinsically compatible with industrial nanoelectronics fabrication methods. In this talk I will discuss the historical development of epigraphene starting in the 1880’s and working up to the present day. I will focus on those aspects that sets graphene apart from other electronic materials as well as our recent discoveries of new ballistic edge states and how their quantum mechanical properties might be utilized in a new generation of electronics that utilizes electronic wave interference, like in optics.
