Electronic structure of single crystal UPd3, UGe2, and USb2 from hard X-ray and angle-resolved photoelectron spectroscopy

Marco Grioni, Luca Moreschini

Electronic structure of single crystal UPd3, UGe2, and USb2 has been measured from hard X-ray photoelectron spectroscopy (HAXPES) with 7.6 keV photons at the European Synchrotron Radiation Facility (ESRF). Lower photon energy angle-resolved photoelectron s ...

Origin and manipulation of the Rashba splitting in surface alloys

Marco Grioni, Luca Moreschini

A novel method is demonstrated to tailor the electronic structure of high-Z surface alloys showing a giant Rashba splitting by means of electron doping. This aims for new model systems to study unconvential spin topologies and for possible applications in ...

Tunable Polaronic Conduction in Anatase TiO2

László Forró, Helmuth Berger, Arnaud Magrez, Marco Grioni, Luca Moreschini, Simon Karl Moser, Jacim Jacimovic

Oxygen vacancies created in anatase TiO2 by UV photons (80–130 eV) provide an effective electron-doping mechanism and induce a hitherto unobserved dispersive metallic state. Angle resolved photoemission reveals that the quasiparticles are large polarons. T ...

A novel quasi-one-dimensional topological insulator in bismuth iodide beta-Bi4I4

László Forró, Marco Grioni, Oleg Yazyev, Gabriel Albert Autes, Andrea Pisoni, Luca Moreschini, Jens Christian Johannsen

Recent progress in the field of topological states of matter(1,2) has largely been initiated by the discovery of bismuth and antimony chalcogenide bulk topological insulators (TIs; refs 3-6), followed by closely related ternary compounds(7-16) and predicti ...

Bulk and surface band structure of the new family of semiconductors BiTeX (X=I, Br, Cl)

Helmuth Berger, Arnaud Magrez, Marco Grioni, Oleg Yazyev, Philippe Bugnon, Alberto Crepaldi, Gabriel Albert Autes, Luca Moreschini, Simon Karl Moser, Jens Christian Johannsen

We present an overview of the new family of semiconductors BiTeX (X = I, Br, Cl) from the perspective of angle resolved photoemission spectroscopy. The strong band bending occurring at the surface potentially endows them with a large flexibility, as they a ...
