Direct Measurement of the Fermi Energy in Graphene Using a Double Layer Structure
Seyoung Kim, Insun Jo, D. C. Dillen +5
We describe a technique which allows a direct measurement of the relative Fermi energy in an electron system using a double layer structure, where graphene is one of the two layers…
Dielectric capping effects on binary and ternary topological insulator surface states
Jiwon Chang, Priyamvada Jadaun, Leonard F. Register +2
Using a density functional based electronic structure method, we study the effect of crystalline dielectrics on the metallic surface states of Bismuth- and chalcogen-based binary a…
Density Functional Study of Ternary Topological Insulator Thin Films
Jiwon Chang, Leonard F. Register, Sanjay K. Banerjee +1
Using an ab-initio density functional theory based electronic structure method with a semi-local density approximation, we study thin-film electronic properties of two topological…
Edge Saturation effects on the magnetism and band gaps in multilayer graphene ribbons and flakes
Bhagawan Sahu, Hongki Min, Sanjay K. Banerjee
Using a density functional theory based electronic structure method and semi-local density approximation, we study the interplay of geometric confinement, magnetism and external el…
Density functional theory based study of graphene and dielectric oxide interfaces
Priyamvada Jadaun, Sanjay K. Banerjee, Leonard F. Register +1
We study the effects of insulating oxides in their crystalline forms on the energy band structure of monolayer and bilayer graphene using a \textit{first principles} density functi…
