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…
Suppression of electron scattering resonances in graphene by quantum dots
M. Krivenkov, D. Marchenko, J. Sánchez-Barriga +2
Transmission of low-energetic electrons through two-dimensional materials leads to unique scattering resonances. These resonances contribute to photoemission from occupied bands wh…
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…
Negative longitudinal magnetoresistance from anomalous N=0 Landau level in topological materials
B. A. Assaf, T. Phuphachong, E. Kampert +8
Negative longitudinal magnetoresistance (NLMR) is shown to occur in topological materials in the extreme quantum limit, when a magnetic field is applied parallel to the excitation…
