Anionic disorder and its impact on the surface electronic structure of oxynitride photoactive semiconductors
Anna Hartl, Ján Minár, Procopios Constantinou +8
The conversion of solar energy into chemical energy, stored in the form of hydrogen, bears enormous potential as a sustainable fuel for powering emerging technologies. Photoactive…
Flat-band hybridization between and states near the Fermi energy of SmCoIn
David W. Tam, Nicola Colonna, Fatima Alarab +4
We present high-quality angle-resolved photoemission (ARPES) and density functional theory calculations (DFT+U) of SmCoIn. We find broad agreement with previously published stu…
Tunable 2D Electron- and 2D Hole States Observed at Fe/SrTiO Interfaces
Pia M. Düring, Paul Rosenberger, Lutz Baumgarten +4
Oxide electronics provide the key concepts and materials for enhancing silicon-based semiconductor technologies with novel functionalities. However, a basic but key property of sem…
Nature of the metallic and in-gap states in Ni-doped SrTiO
Fatima Alarab, Karol Hricovini, Berengar Leikert +6
Epitaxial thin films of SrTiO(100) doped with 6% and 12% Ni are studied with resonant angle-resolved photoelectron spectroscopy (ARPES) at the Ti and Ni L2,3-edges. We find tha…
k-dependent proximity-induced modulation of spin-orbit interaction in MoSe2 interfaced with amorphous Pb
Fatima Alarab, Ján Minár, Procopios Constantinou +4
The ability to modulate the spin-orbit (SO) interaction is crucial for engineering a wide range of spintronics-based quantum devices, extending from state-of-the-art data storage t…
Altermagnetic lifting of Kramers spin degeneracy
J. Krempaský, L. Šmejkal, S. W. D'Souza +20
Lifted Kramers spin-degeneracy has been among the central topics of condensed-matter physics since the dawn of the band theory of solids. It underpins established practical applica…
Charge fluctuations in the intermediate-valence ground state of SmCoIn
David W. Tam, Nicola Colonna, Neeraj Kumar +9
The microscopic mechanism of heavy band formation, relevant for unconventional superconductivity in CeCoIn and other Ce-based heavy fermion materials, depends strongly on the e…
Orientation-dependent electron-phonon coupling in interfacial superconductors LaAlO3/KTaO3
Xiaoyang Chen, Tianlun Yu, Yuan Liu +17
The emergent superconductivity at the LaAlO3/KTaO3 interfaces exhibits a mysterious dependence on the KTaO3 crystallographic orientations. Here we show, by soft X-ray angle-resolve…
Are high-energy photoemission final states free-electron-like?
V. N. Strocov, L. L. Lev, F. Alarab +6
Three-dimensional (3D) electronic band structure is fundamental for understanding a vast diversity of physical phenomena in solid-state systems, including topological phases, inter…
Photoemission study on pristine and Ni-doped SrTiO thin films
F. Alarab, K. Hricovini, B. Leikert +12
We combined photoelemission spectroscopy with first-principle calculations to investigate structural and electronic properties of SrTiO doped with Ni impurities. In SrTiO$_{3…
