Tuning a Schottky barrier in a photoexcited topological insulator with transient Dirac cone electron-hole asymmetry
M. Hajlaoui, E. Papalazarou, J. Mauchain +19
The advent of Dirac materials has made it possible to realize two dimensional gases of relativistic fermions with unprecedented transport properties in condensed matter. Their phot…
Dirac cone with helical spin polarization in ultrathin -Sn(001) films
Yoshiyuki Ohtsubo, Patrick Le Fèvre, François Bertran +1
Spin-split two-dimensional electronic states have been observed on ultrathin Sn(001) films grown on InSb(001) substrates. Angle-resolved photoelectron spectroscopy (ARPES) performe…
Topological surface states of strained Mercury-Telluride probed by ARPES
Olivier Crauste, Yoshiyuki Ohtsubo, Philippe Ballet +6
The topological surface states of strained HgTe have been measured using high-resolution ARPES measurements. The dispersion of surface states form a Dirac cone, which origin is clo…
Nature of the bad metallic behavior of Fe_{1.06}Te inferred from its evolution in the magnetic state
Ping-Hui Lin, Y. Texier, A. Taleb-Ibrahimi +5
We investigate with angle resolved photoelectron spectroscopy the change of the Fermi Surface (FS) and the main bands from the paramagnetic (PM) state to the antiferromagnetic (AFM…
Non-trivial Surface-band Dispersion on Bi(111)
Yoshiyuki Ohtsubo, Luca Perfetti, Mark Oliver Goerbig +3
We performed angle-resolved photoelectron spectroscopy of the Bi(111) surface to demonstrate that this surface support edge states of non-trivial topology. Along the …
Large temperature dependence of the number of carriers in Co-doped BaFe2As2
V. Brouet, Ping-Hui Lin, Y. Texier +10
Using angle-resolved photoemission spectroscopy, we study the evolution of the number of carriers in Ba(Fe(1-x)Cox)2As2 as a function of Co content and temperature. We show that th…
