Controllable magnetic doping of the surface state of a topological insulator
T. Schlenk, M. Bianchi, M. Koleini +11
A combined experimental and theoretical study of doping individual Fe atoms into Bi2Se3 is presented. It is shown through a scanning tunneling microscopy study that single Fe atoms…
Evidence for a direct band gap in the topological insulator Bi2Se3 from theory and experiment
I. A. Nechaev, R. C. Hatch, M. Bianchi +8
Using angle-resolved photoelectron spectroscopy and ab-initio GW calculations, we unambiguously show that the widely investigated three-dimensional topological insulator Bi2Se3 has…
Robust Surface Doping of BiSe by Rb Intercalation
Marco Bianchi, Richard C. Hatch, Zheshen Li +11
Rubidium adsorption on the surface of the topological insulator BiSe is found to induce a strong downward band bending, leading to the appearance of a quantum-confined two…
The electronic structure of clean and adsorbate-covered Bi2Se3: an angle-resolved photoemission study
Marco Bianchi, Richard C. Hatch, Dandan Guan +4
Angle-resolved photoelectron spectroscopy is used for a detailed study of the electronic structure of the topological insulator Bi2Se3. Nominally stoichiometric and calcium-doped s…
