| 520 | _ | _ | |a In structure inversion-asymmetric environments such as surfaces and interfaces the spin of quasiparticles can have a profound effect on their interference. Quasiparticle interference patterns measured typically by scanning tunneling microscopy are not related in a trivial way to the dispersion of the electronic states. In fact, for Bi(110) [1] it could be shown that the observed interference patterns can be interpreted only by taking spin-conserving scattering events into account. In this contribution we go one step further and include explicitly in the analysis the scattering of the helical surface state electrons off single non-magnetic and magnetic impurities at the surface of the strong topological insulator Bi2Te3. As a matter of principle, magnetic impurities at surfaces break the protection against backscattering. We study this loss of protection by density-functional calculations of the quasiparticle interference at surfaces due to scattering, taking into account time-reversed transitions caused by the magnetic moment. Finally we will also comment on the effect of impurities in the bulk with a focus on the emergence of impurity bands. In our calculations we employ the KKR-Green function method for the electronic structure and scattering properties at defects [2, 3].
