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…
Two-dimensional electron systems in perovskite oxide heterostructures: Role of the polarity-induced substitutional defects
Shih-Chieh Lin, Cheng-Tai Kuo, Yu-Cheng Shao +17
The discovery of a two-dimensional electron system (2DES) at the interfaces of perovskite oxides such as LaAlO3 and SrTiO3 has motivated enormous efforts in engineering interfacial…
Hard x-ray standing-wave photoemission insights into the structure of an epitaxial Fe/MgO multilayer magnetic tunnel junction
C. S. Conlon, G. Conti, S. Nemšák +15
The Fe/MgO magnetic tunnel junction is a classic spintronic system, with current importance technologically, and interest for future innovation. The key magnetic properties are lin…
Characterization of free standing InAs quantum membranes by standing wave hard x-ray photoemission spectroscopy
G. Conti, S. Nemšák, C. -T. Kuo +13
Free-standing nanoribbons of InAs quantum membranes (QMs) transferred onto a (Si/Mo) multilayer mirror substrate are characterized by hard x-ray photoemission spectroscopy (HXPS),…
Accurate determination of the valence band edge in hard x-ray photoemission spectra using GW theory
Johannes Lischner, Slavomir Nemsak, Giuseppina Conti +6
We introduce a new method for determining accurate values of the valence-band maximum in x-ray photoemission spectra. Specifically, we align the sharpest peak in the valence-band r…
