The NSF (NIRT) / Intel funded NPEG project at the Georgia Institute of
Technology explores the properties of nanopatterened graphene. Ultrathin
layers of graphite
(from 1 to several dozen atoms think) are epitaxially grown on single
crystal silicon carbide. The graphene layers are nanopatterend using standard
lithography methods to produce electronically functional structures.
Nanographene electronic properties are closely related to those of carbon
nanotubes. Recent results include quantum coherence effects, a room temperature
transistor-like device, and magneto-transport measurements showing room
temperature mobilities exceeding 6000 cm^2 / V s
Clusters are small agreggates of 2 - ~100,000 atoms held together
by various cohesive forces. In many cases their electrical, magnetic,
and optical properties differ significantly from those of the bulk
material. They are a useful experimental platform for
investigating the emergence of bulk properties and have the potential
for many technological applications.
