DESCRIPTION:Prof. Jürg Osterwalder\, Physik-Institut\, Universität Zür
 ich\nThe spin-orbit interaction in combination with the breaking of spatia
 l inversion symmetry can lead to spin-splitting of two-dimensional electro
 nic states at surfaces or interfaces of non-magnetic materials.\nThis so-c
 alled Rashba effect is exploited in concept of the spin field-effect trans
 istor. In topological insulators\, the non-trivial topology of the bulk el
 ectronic states forces the appearance of spin-polarized surface states. In
  both cases\, the directions of spin polarization and electron momentum ar
 e strictly locked\, leading of a plethora of unusual properties and physic
 al phenomena.\nThis talk focusses on the characterization of the spin prop
 erties of these surface states by spin-resolved ARPES.
