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…
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 …
