Bulk-to-surface misorientation and the spin texture of topological insulators
N. Klier, F. Rost, R. Gupta +3
Weak topological insulators possess a symmetry related set of Dirac-Weyl cones in the surface Brillouin zone, implying misorientation between the principle axis of the low energy m…

Bulk physics entwined with a topological surface state
N. Klier, S. Sharma, O. Pankratov +1
For the IV-VI semiconductor family we derive an exact relation between the microscopic gap edge wave functions of the bulk insulator and the Dirac-Weyl topological surface state wa…
