Dimensionality-tuned electronic structure of nickelate superlattices explored by soft-x-ray angle resolved photoelectron spectroscopy
G. Berner, M. Sing, F. Pfaff +13
The electronic and magnetic properties of epitaxial LaNiO3/LaAlO3 superlattices can be tuned by layer thickness and substrate-induced strain. Here, we report on direct measurements…
Direct k-space mapping of the electronic structure in an oxide-oxide interface
G. Berner, M. Sing, H. Fujiwara +11
The interface between LaAlO3 and SrTiO3 hosts a two-dimensional electron system of itinerant carriers, although both oxides are band insulators. Interface ferromagnetism coexisting…
Unoccupied electronic structure of TiOCl studied by x-ray absorption near-edge spectroscopy
Sebastian Glawion, Maurits W. Haverkort, Götz Berner +6
We study the unoccupied electronic structure of the spin-1/2 quantum magnet TiOCl by x-ray absorption near-edge spectroscopy (XANES) at the Ti L and O K edges. Data is acquired bot…
Photoemission of a doped Mott insulator: spectral weight transfer and qualitative Mott-Hubbard description
M. Sing, S. Glawion, M. Schlachter +5
The spectral weight evolution of the low-dimensional Mott insulator TiOCl upon alkali-metal dosing has been studied by photoelectron spectroscopy. We observe a spectral weight tran…
Profiling the interface electron gas of LaAlO3/SrTiO3 heterostructures by hard X-ray photoelectron spectroscopy
M. Sing, G. Berner, K. Goss +11
The conducting interface of LaAlO/SrTiO heterostructures has been studied by hard X-ray photoelectron spectroscopy. From the Ti~2 signal and its angle-dependence we deri…
