Mapping the band structure of GeSbTe phase change alloys around the Fermi level
Jens Kellner, Gustav Bihlmayer, Marcus Liebmann +16
Phase change alloys are used for non-volatile random access memories exploiting the conductivity contrast between amorphous and metastable, crystalline phase. However, this contras…
Evolution of remnant Fermi surface state in lightly-doped correlated spin-orbit insulator SrLaIrO
K. Terashima, M. Sunagawa, H. Fujiwara +14
Electronic structure has been studied in lightly electron doped correlated spin-orbit insulator SrIrO by angle-resolved photoelectron spectroscopy. We have observed coexist…
Laser-induced persistent photovoltage on the surface of a ternary topological insulator at room temperature
J. Sánchez-Barriga, M. Battiato, E. Golias +4
Using time- and angle-resolved photoemission, we investigate the ultrafast response of excited electrons in the ternary topological insulator (BiSb)Te to fs-i…
Sub-picosecond spin dynamics of excited states in the topological insulator BiTe
J. Sánchez-Barriga, M. Battiato, M. Krivenkov +9
Using time-, spin- and angle-resolved photoemission, we investigate the ultrafast spin dynamics of hot electrons on the surface of the topological insulator BiTe following…
Nonmagnetic band gap at the Dirac point of the magnetic topological insulator (BiMnSe
J. Sánchez-Barriga, A. Varykhalov, G. Springholz +17
Magnetic doping is expected to open a band gap at the Dirac point of topological insulators by breaking time-reversal symmetry and to enable novel topological phases. Epitaxial (Bi…
Absence of Giant Spin Splitting in the Two-Dimensional Electron Liquid at the Surface of SrTiO (001)
S. McKeown Walker, S Riccò, F. Y. Bruno +10
We reinvestigate the putative giant spin splitting at the surface of SrTiO reported by Santander-Syro [Nature Mat. 13, 1085 (2014)]. Our spin- and angle-resolved photo…
