The study was motivated by the extraordinarily high conductivity of the non-magnetic delafossites PdCoO2 and PtCoO2, the measurement of whose electronic structure is reported and discussed. Two unexpected effects were observed in the course of the investigation; each is described and analysed in detail. Firstly, a previously unrecognised type of spectroscopic signal, allowing the non-magnetic probe of photoemission to become sensitive to spin-spin correlations, was observed in the antiferromagnetic PdCrO2. Its origin was identified as the Kondo-like coupling of itinerant and Mott insulating electrons. Furthermore, surface states exhibiting an unusually large Rashba-like spin-splitting were observed on the transition metal terminated surfaces of delafossites. The large inversion symmetry breaking energy scale, a consequence of the unusual structure of the surface layer, is identified as the origin of the effect.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Solid state physicsSpectrum analysisMicroscopyMaterials—SurfacesThin filmsSolid State Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P25013Spectroscopy and Microscopyhttps://scigraph.springernature.com/ontologies/product-market-codes/P31090Surfaces and Interfaces, Thin Filmshttps://scigraph.springernature.com/ontologies/product-market-codes/Z19000Spectroscopy/Spectrometryhttps://scigraph.springernature.com/ontologies/product-market-codes/C11020Solid state physics.Spectrum analysis.Microscopy.Materials—Surfaces.Thin films.Solid State Physics.Spectroscopy and Microscopy.Surfaces and Interfaces, Thin Films.Spectroscopy/Spectrometry.530.41530.41Sunko Veronikaauthttp://id.loc.gov/vocabulary/relators/aut1064762MiAaPQMiAaPQMiAaPQBOOK9910349507003321Angle Resolved Photoemission Spectroscopy of Delafossite Metals2540570UNINA
