Emergent phenomena at oxide interfaces studied with standing-wave photoelectron spectroscopy
C. -T. Kuo, G. Conti, J. E. Rault +3
Emergent phenomena at complex-oxide interfaces have become a vibrant field of study in the past two decades due to the rich physics and a wide range of possibilities for creating n…
Near total reflection X-ray photoelectron spectroscopy: Quantifying chemistry at solid/liquid and solid/solid interfaces
Henrique P. Martins, Giuseppina Conti, Isvar Cordova +9
Near total reflection regime has been widely used in X-ray science, specifically in grazing incidence small angle X-ray scattering and in hard X-ray photoelectron spectroscopy. In…
Orbital contributions in the element-resolved valence electronic structure of Bi2Se3
Cheng-Tai Kuo, Shih-Chieh Lin, Jean-Pascal Rueff +9
In this work, we studied the bulk band structure of a topological insulator (TI) Bi2Se3 and determined the contributions of the Bi and Se orbital states to the valence bands using…
High resolution depth profiling using near-total-reflection hard X-ray photoelectron spectroscopy
Julien E. Rault, Cheng-Tai Kuo, Henrique P. Martins +2
By adjusting the incidence angle of incoming X-ray near the critical angle of X-ray total reflection, the photoelectron intensity is strongly modulated due to the variation of X-ra…
Bulk Electronic Structure of Lanthanum Hexaboride (LaB6) by Hard X-ray Angle-Resolved Photoelectron Spectroscopy
A. Rattanachata, L. Nicolaï, H. P. Martins +11
In the last decade rare-earth hexaborides have been investigated for their fundamental importance in condensed matter physics, and for their applications in advanced technological…
Hard x-ray standing-wave photoemission study of the interfaces in a BiFeO/LaSrMnO superlattice
H. P. Martins, S. A. Khan, G. Conti +12
Hybrid multiferroics such as BiFeO (BFO) and LaSrMnO (LSMO) heterostructures are highly interesting functional systems due to their complex electronic and m…
