Journal ArticleDOI
Illuminating the dark corridor in graphene: polarization dependence of angle-resolved photoemission spectroscopy on graphene
TL;DR: In this paper, angle-resolved photoemission spectroscopy (ARPES) was used to image the electronic structure of epitaxial graphene near the (K) over bar point.
Journal ArticleDOI
Spin-orbit split two-dimensional electron gas with tunable Rashba and Fermi energy
Christian R. Ast,Christian R. Ast,Daniela Pacilé,Luca Moreschini,Mihaela C. Falub,Marco Papagno,Klaus Kern,Klaus Kern,Marco Grioni,Jürgen Henk,Arthur Ernst,Sergey Ostanin,Patrick Bruno +12 more
TL;DR: In this paper, it is shown that it is possible to tune the Rashba energy and the Fermi energy in a two-dimensional electron gas by a controlled change of stoichiometry in an artificial surface alloy.
Journal ArticleDOI
Complex Spin Texture in the Pure and Mn-Doped Topological Insulator Bi2Te3
Jürgen Henk,Arthur Ernst,Sergey V. Eremeev,Sergey V. Eremeev,Evgueni V. Chulkov,Evgueni V. Chulkov,Evgueni V. Chulkov,Igor V. Maznichenko,Ingrid Mertig,Ingrid Mertig +9 more
TL;DR: It is shown by first-principles calculations that the surface state of the insulator Bi2Te3 survives upon moderate Mn doping of the surface layers, showing layer-dependent spin reversal and spin vortices.
Journal ArticleDOI
Hybridization between the unoccupied Shockley surface state and bulk electronic states on Cu(111)
Ahmet Unal,Christian Tusche,S. Ouazi,Sebastian Wedekind,Cheng-Tien Chiang,Aimo Winkelmann,Dirk Sander,Jürgen Henk,J. Kirschner +8 more
TL;DR: In this paper, the dispersion of the occupied and unoccupied Shockley surface state of Cu(111) was investigated and the authors ascribe this deviation to the shift of the spectral weight of the surface state into the bulk and of bulk states toward the surface, which leads to an enhanced hybridization between the states with increasing energy.
Journal ArticleDOI
Interference of spin states in photoemission from Sb/Ag(111) surface alloys
Fabian Meier,Fabian Meier,V. N. Petrov,Hossein Mirhosseini,Luc Patthey,Jürgen Henk,Jürg Osterwalder,J. Hugo Dil,J. Hugo Dil +8 more
TL;DR: In this paper, a three-dimensional spin polarimeter was used to study the interference of spin states in photoemission from the surface alloy Sb/Ag(111), which features a small spin splitting of a size comparable to the momentum broadening of the quasiparticles, thus causing an intrinsic overlap between states with orthogonal spinors.
