Proposal of a one-dimensional electron gas in the steps at the LaAlO-SrTiO interface
N. C. Bristowe, T. Fix, M. G. Blamire +2
The two-dimensional electron gas (2DEG) at the interface between LaAlO (LAO) and SrTiO (STO) has become one of the most fascinating and highly-debated oxide systems of rece…
Theoretical and numerical investigation of the size-dependent optical effects in metal nanoparticles
Alexander A. Govyadinov, George Y. Panasyuk, John C. Schotland +1
We further develop the theory of quantum finite-size effects in metallic nanoparticles, which was originally formulated by Hache, Ricard and Flytzanis [J. Opt. Soc. Am. B 3, 1647 (…
Evidence of defect-induced ferromagnetism in ZnFeO thin films
C. E. Rodríguez Torres, F. Golmar, M. Ziese +2
X-ray absorption near-edge and grazing incidence X-ray fluorescence spectroscopy are employed to investigate the electronic structure of ZnFeO thin films. The spectrosc…
Adiabatic-Connection-Fluctuation-Dissipation approach to the long-range behavior of the exchange-correlation energy at metal surfaces: A numerical study for jellium slabs
Lucian A. Constantin, J. M. Pitarke
A still open issue in many-body theory is the asymptotic behavior of the exchange-correlation energy and potential in the vacuum region of a metal surface. Here we report a numeric…
