This thesis describes the construction of a rotatable
spin-polarized electron source and its use in spin- and
angle-resolved inverse photoemission to investigate the unoccupied
electron states of Tl/Si(111)-(1x1) with special emphasis on their
spin texture. Towards more efficient electronics - with the
electron spin as information carrier: This motto is the motivation
for numerous studies in solid state physics that deal with electron
states whose spin degeneracy is lifted by spin-orbit interaction.
This thesis addresses the spin-orbit-induced spin textures in
momentum space in the surface electronic structure of a
prototypical Rashba-type hybrid system: heavy metal thallium on
semiconducting silicon. For Tl/Si(111)-(1x1), the thallium adlayer
provides surface states with strong spin-orbit interaction and
peculiar spin-orbit-induced spin textures: spin rotations and spin
chirality in momentum space for unoccupied surface states with
giant spin splittings. Almost completely out-of-plane
spin-polarized valleys in the vicinity of the Fermi level are
identified. As the valley polarization is oppositely oriented at
specific points in momentum space, backscattering should be
strongly suppressed in this system.
