Minority-spin states and the degree of spin polarization in ferromagnetic metallic LaSrMnO ()
Z. Sun, Q. Wang, J. F. Douglas +10
Using angle-resolved photoemission spectroscopy (ARPES), we investigate the electronic band structure and Fermi surface of ferromagnetic LaSrMnO (…
The electronic structure of the high-symmetry perovskite iridate Ba2IrO4
S. Moser, L. Moreschini, A. Ebrahimi +11
We report angle-resolved photoemission (ARPES) measurements, density functional and model tight-binding calculations on BaIrO (Ba-214), an antiferromagnetic ( K) i…
Momentum-resolved electronic structure at a buried interface from soft x-ray standing-wave angle-resolved photoemission
A. X. Gray, J. Minár, L. Plucinski +19
Angle-resolved photoemission spectroscopy (ARPES) is a powerful technique for the study of electronic structure, but it lacks a direct ability to study buried interfaces between tw…
Elemental Topological Insulator with a Tunable Fermi Level: Strained α-Sn on InSb(001)
A. Barfuss, L. Dudy, M. R. Scholz +16
We report on the epitaxial fabrication and electronic properties of a topological phase in strained α-Sn on InSb. The topological surface state forms in the presence of an unusual…
Dimensional crossover of the electronic structure in LaNiO3 ultrathin films: Orbital reconstruction, Fermi surface nesting, and the origin of the metal-insulator transition
Hyang Keun Yoo, Seung Ill Hyun, Luca Moreschini +9
Dimensionality control in the LaNiO3 (LNO) heterostructure has attracted attention due to its two-dimensional (2D) electronic structure was predicted to have an orbital ordered ins…
Tunable polaronic conduction in anatase TiO2
S. Moser, L. Moreschini, J. Jacimovic +9
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. Angl…
