In recent years spin- and angle-resolved photoemission (SARPES) have proven
to be a powerful tool for the investigation of spin effects on surfaces.
After an overview of the possibilities and challenges of SARPES I will
present some of our recent results on low-dimensional systems with strong
spin-orbit interaction. A prime example of how little is still understood
about the role of the spin in the photoemission process is formed by the
observation of spin interference in photoemission from long range ordered Sb
on Ag(111) surface alloys. After this basic quantum mechanical principle I
will quickly review my experimentalist understanding of topological
insulators and present our SARPES results on these only recently discovered
new material phases. Examples will include both binary and tertiary
compounds.
