Anomalous behavior of the electronic structure of (Bi $_{1 - x}$ In $_{x}$ ) $_{2}$ Se $_{3}$ 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 (Bi $_{1 - x}$ In $_{x}$ ) $_{2}$ Se $_{3}$ bulk s…

Band renormalization of blue phosphorus on Au(111)

E. Golias, M. Krivenkov, A. Varykhalov +2

Most recently, theoretical calculations predicted the stability of a novel two-dimensional phosphorus honeycomb lattice named blue phosphorus. Here, we report on the growth of blue…

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 (Bi $_{1 x}$ Sb $_{x}$ ) $_{2}$ Te $_{3}$ to fs-i…

Sub-picosecond spin dynamics of excited states in the topological insulator Bi $_{2}$ Te $_{3}$

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 Bi $_{2}$ Te $_{3}$ 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…

Nonmagnetic band gap at the Dirac point of the magnetic topological insulator (Bi $_{1 - x}$ Mn $_{x})_{2}$ Se $_{3}$

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…
