It has been predicted that gold, aluminum, and copper do not fundamentally change the graphene band structure when they are in close proximity to graphene, but merely increase the doping. My data confirms this prediction, ...

After the pioneering investigations into graphene-based electronics at Georgia Tech, great strides have been made developing epitaxial graphene on silicon carbide (EG) as a new electronic material. EG has not only demonstrated ...

Graphene attracted a great deal of public interest because of its novel electrical characteristics, structural integrity, high electron mobility, and most important for my work, it was shown to be a room temperature ballistic ...

One material that has drawn much attention as a viable supplementary material to silicon is graphene, an atom-thick sheet of carbon in a hexagonal lattice. Graphene has many desirable qualities, including massless Dirac ...

In this thesis, we show that planar graphene ribbons have properties similar to those of nanotubes. Both exhibit semiconducting or metallic properties depending on crystal orientation. The band gap varies approximately as ...

For the past decade, graphene has been among the most heavily researched materials in condensed matter physics. In particular, its unusual electronic properties have spurred researchers to investigate new applications and ...

Twisted bilayers of graphene have shown strikingly rich phenomenology while also posing significant theoretical challenges. As a consequence, many numerically discovered phenomena have defied analytical understanding to ...

Two-dimensional (2D) materials have drawn much attention because of their superior and unique properties. Undoubtedly, the most well-known 2D material is graphene, an atomic-thick sheet of carbon in a honeycomb lattice. ...

Realizing a technologically relevant graphene semiconductor has been one of the key challenges for advancing graphene electronics. Recently, a semiconducting form of graphene was discovered in the first graphene layer that ...
