A consistent view of the samarium hexaboride terminations to resolve the nature of its surface states
H. Herrmann, P. Hlawenka, K. Siemensmeyer +11
The research effort prompted by the prediction that SmB could be the first topological Kondo insulator has produced a wealth of new results, though not all of these seem compat…
Impact of ultrafast transport on the high-energy states of a photoexcited topological insulator
F. Freyse, M. Battiato, L. V. Yashina +1
Ultrafast dynamics in three-dimensional topological insulators (TIs) opens new routes for increasing the speed of information transport up to frequencies thousand times faster than…
Ferrimagnetic nanostructures for magnetic memory bits
A. A. Ünal, S. Valencia, D. Marchenko +4
Increasing the magnetic data recording density requires reducing the size of the individual memory elements of a recording layer as well as employing magnetic materials with temper…
Anisotropic effect of warping on the lifetime broadening of topological surface states in angle-resolved photoemission from BiTe
J. Sánchez-Barriga, M. R. Scholz, E. Golias +5
We analyze the strong hexagonal warping of the Dirac cone of BiTe by angle-resolved photoemission. Along , the dispersion deviates from a line…
Observation of Quantum-Tunneling Modulated Spin Texture in Ultrathin Topological Insulator Bi2Se3 Films
Madhab Neupane, Anthony Richardella, Jaime Sánchez-Barriga +18
Understanding the spin-texture behavior of boundary modes in ultrathin topological insulator films is critically essential for the design and fabrication of functional nano-devices…
Photoemission of BiSe with Circularly Polarized Light: Probe of Spin Polarization or Means for Spin Manipulation?
J. Sánchez-Barriga, A. Varykhalov, J. Braun +12
Topological insulators are characterized by Dirac cone surface states with electron spins aligned in the surface plane and perpendicular to their momenta. Recent theoretical and ex…
Evidence for topological band inversion of the phase change material Ge2Sb2Te5
Christian Pauly, Marcus Liebmann, Alessandro Giussani +8
We present an angle-resolved photoemission study of a ternary phase change material, namely Ge2Sb2Te5, epitaxially grown on Si(111) in the metastable cubic phase. The observed uppe…
Massless Dirac fermions in epitaxial graphene on Fe(110)
A. Varykhalov, J. Sánchez-Barriga, P. Hlawenka +1
Graphene grown on Fe(110)by chemical vapor deposition using propylene is investigated by means of angle-resolved photoemission. The presence of massless Dirac fermions is clearly e…
Hedgehog Spin-texture and Berry's Phase tuning in a Magnetic Topological Insulator
Su-Yang Xu, Madhab Neupane, Chang Liu +18
Understanding and control of spin degrees of freedom on the surfaces of topological materials are key to future applications as well as for realizing novel physics such as the axio…
