Hybrid exchange-correlation functional for accurate prediction of the electronic and structural properties of ferroelectric oxides
D. I. Bilc, R. Orlando, R. Shaltaf +3
Using a linear combination of atomic orbitals approach, we report a systematic comparison of various Density Functional Theory (DFT) and hybrid exchange-correlation functionals for…
New ultrasmall iron-oxide nanoparticles with high magnetisation as potential T1-MRI contrast agents for Molecular Imaging
Elena Taboada, Elisenda Rodriguez, Anna Roig +3
Here we report on the synthesis of very small gamma-Fe2O3 nanoparticles (5 nm) presenting very narrow particle size distribution and exceptionally high saturation magnetisation. Th…
On the use of photometric redshifts for X-ray selected AGNs
S. Kitsionas, E. Hatziminaoglou, A. Georgakakis +1
(Abridged) In this paper we present photometric redshift estimates for a sample of X-ray selected sources detected in the wide field (~2 deg^2), bright [f_{X} (0.5-8 keV)~10^{-14}…
QSO Photometric Redshift estimation for the XMM-Newton/2dF Survey
S. Kitsionas, E. Hatziminaoglou, I. Georgantopoulos +2
The technique of estimating redshifts using photometric rather than spectroscopic observations has recently received great attention due to its simplicity and the accuracy of the r…
First-principles calculation of the band offset at BaO/BaTiO and SrO/SrTiO interfaces
Javier Junquera, Magali Zimmer, Pablo Ordejon +1
We report first-principles density-functional pseudopotential calculations on the atomic structures, electronic properties, and band offsets of BaO/BaTiO and SrO/SrTiO nano…
