Theme 3 – Carbon Electronics
Lead: Prof Philip Kim (Columbia)
FENA was one of the first groups to engage and explore the fundamental discoveries of graphene for carbon electronics; we have also been a catalyst for the CERA program and have developed a core competency in this area. Our research in carbon electronics will advance further towards transforming a carbon nanotube platform into a usable wafer scale substrate for large scale integrated circuit compatibility. Likewise, we will take advantage of newly discovered routes such as ‘unzipping’ CNTs to form nanoribbons and also unique surface passivation of Si with alkyl groups to obtain graphene. We propose to study quantum transport phenomena in lateral graphene heterojunctions and the unique properties of bilayer graphene for gate controlled collective tunneling devices to minimize variability and noise. In addition, we will study terahertz graphene plasmonics, which are inherently related to high speeds and may well lead to extremely low power novel device applications. Combining graphene with highly correlated electron materials, we will explore the possibility of creating electric-field controlled nonvolatile logics. Our approach to carbon materials and devices is complementary to those found in the Structures and Devices Focus Center.
