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…
Anomalous behavior of the electronic structure of (BiIn)Se across the quantum-phase transition from topological to trivial insulator
J. Sánchez-Barriga, I. Aguilera, L. V. Yashina +9
Using spin- and angle-resolved spectroscopy and relativistic many-body calculations, we investigate the evolution of the electronic structure of (BiIn)Se bulk s…
Quasi-two-dimensional thermoelectricity in SnSe
V. Tayari, B. V. Senkovskiy, D. Rybkovskiy +14
Stannous selenide is a layered semiconductor that is a polar analogue of black phosphorus, and of great interest as a thermoelectric material. Unusually, hole doped SnSe supports a…
High-temperature quantum oscillations of the Hall resistance in bulk BiSe
Marco Busch, Olivio Chiatti, Sergio Pezzini +5
Helically spin-polarized Dirac fermions (HSDF) in protected topological surface states (TSS) are of high interest as a new state of quantum matter. In three-dimensional (3D) materi…
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…
