Graphene near commensuration
(Georgia Institute of Technology, 2018-04-05)
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 ...
Theory of resonance and novel nonperturbative physics in twisted bilayer graphene
(Georgia Institute of Technology, 2017-04-06)
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 ...
Transport in graphene tunnel junctions
(Georgia Institute of Technology, 2011-06-20)
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, ...
Structured epitaxial graphene for electronics
(Georgia Institute of Technology, 2012-06-28)
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 ...
Structure and properties of incommensurate and commensurate phases of graphene on SiC(0001)
(Georgia Institute of Technology, 2017-05-19)
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 ...
Studies of epitaxial graphene and silicon growth on silicon carbide under silane gas
(Georgia Institute of Technology, 2017-04-07)
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. ...
Improved growth, ordering, and characterization of sidewall epitaxial graphene nanoribbons
(Georgia Institute of Technology, 2016-06-03)
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 ...
Magneto-optical study of correlated electron materials in high magnetic fields
(Georgia Institute of Technology, 2014-01)
Edge state characterization of epitaxial graphene nanoribbons and modifications of the electrical structure of buffer graphene after aluminum oxide deposition
(Georgia Institute of Technology, 2020-02-11)
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 ...
Exploring Quantum Electronic Transport in Flatland
(Georgia Institute of Technology, 2017-04-10)
Over the past decade, the physics of low dimensional electronic systems has been revolutionized by the discovery of materials with very unusual electronic properties where the behavior of the electrons is governed by the ...
