Controlling the effective mass of quantum well states in Pb/Si(111) by interface engineering
Bartosz Slomski, Fabian Meier, Juerg Osterwalder +1
The in-plane effective mass of quantum well states in thin Pb films on a Bi reconstructed Si(111) surface is studied by angle-resolved photoemission spectroscopy. It is found that…
Observation of Topological Order in the TlBiSe2 class : Probing the "spin" and "phase" on topological insulator surfaces
Su-Yang Xu, L. A. Wray, Y. Xia +9
A topological insulator is characterized by spin-momentum locking on its boundary. The spin momentum locking on the surface of a three dimensional topological insulator leads to th…
Spin and angular resolved photoemission experiments on epitaxial graphene
Isabella Gierz, Jan Hugo Dil, Fabian Meier +6
Our recently reported spin and angular resolved photoemission (SARPES) results on an epitaxial graphene monolayer on SiC(0001) suggested the presence of a large Rashba-type spin sp…
