TL;DR: In this article, the authors show that a third manipulation handle is accessible by utilizing the amount of super-band-gap light a topological insulator surface has been exposed to under typical ARPES experimental conditions.
Angle-resolved and core-level photoemission study of interfacing the topological insulator Bi1.5Sb0.5Te1.7Se1.3 with Ag, Nb, and Fe
N. de Jong,Emmanouil Frantzeskakis,B. Zwartsenberg,Yingkai Huang,D. Wu,P. Hlawenka,Jaime Sánchez-Barriga,Andrei Varykhalov,E. van Heumen,Mark S. Golden +9 more
TL;DR: In this article, the authors studied the effects of the overlayer growth on the occupied electronic structure of the topological insulator (TI) and showed that the chemical potential first moves downward (p-type dopant behavior) and then upward (n-type behavior) on increasing coverage.

TL;DR: In this paper, a high-field magnetotransport study on selected low-carrier crystals of the topological insulator Bi2−xSbxTe3−ySey was performed.
Micro-metric electronic patterning of a topological band structure using a photon beam.

TL;DR: In this paper, an EUV light beam of moderate flux was used to exclude these topologically trivial states from the Fermi level of Bi1.46Sb0.54Te1.7Se1.3 single crystals, thereby re-establishing the purely topological character of the low lying electronic states of the system.
