Structural and electronic properties of highly doped topological insulator Bi2Se3 crystals
Helin Cao, Suyang Xu, Ireneusz Miotkowski +4
We present a study of the structural and electronic properties of highly doped topological insulator Bi2Se3 single crystals synthesized by the Bridgman method. Lattice structural c…
Topological insulator Bi2Te3 films synthesized by metal organic chemical vapor deposition
Helin Cao, Rama Venkatasubramanian, Chang Liu +5
Topological insulator (TI) materials such as Bi2Te3 and Bi2Se3 have attracted strong recent interests. Large scale, high quality TI thin films are important for developing TI-based…
Interplay between ferromagnetism, surface states, and quantum corrections in a magnetically doped topological insulator
Duming Zhang, Anthony Richardella, David W. Rench +12
The breaking of time-reversal symmetry by ferromagnetism is predicted to yield profound changes to the electronic surface states of a topological insulator. Here, we report on a co…
An isolated Dirac cone on the surface of ternary tetradymite-like topological insulators
H. Lin, Tanmoy Das, L. A. Wray +3
We have extended the search for topological insulators to the ternary tetradymite-like compounds M2X2Y (M = Bi or Sb; X and Y = S, Se or Te), which are variations of the well-known…
Graphene growth on h-BN by Molecular Beam Epitaxy
Jorge M. Garcia, Ulrich Wurstbauer, Antonio Levy +10
The growth of single layer graphene nanometer size domains by solid carbon source molecular beam epitaxy on hexagonal boron nitride (h-BN) flakes is demonstrated. Formation of sing…
Effect of 3d-doping on the electronic structure of BaFe2As2
J. A. McLeod, A. Buling, R. J. Green +10
The electronic structure of BaFe2As2 doped with Co, Ni, and Cu has been studied by a variety of experimental and theoretical methods, but a clear picture of the dopant 3d states ha…
