Emergence of superconductivity in single-crystalline LaFeAsO under simultaneous Sm and P substitution
Nikolai D. Zhigadlo, Roman Puzniak, Philip J. W. Moll +2
We report on the high-pressure growth, structural characterization, and investigation of the electronic properties of single-crystalline LaFeAsO co-substituted by Sm and P, in both…
Thermal transport in ultrathin Si nanowires: a first principles study
Konstanze R. Hahn, Claudio Melis, Fabio Bernardini +2
Phonon properties of small Si nanowires in [110] direction have been analyzed using density functional perturbation theory. Several samples with varying diameters ranging from 0.38…
Ab initio many-body GW correlations in the electronic structure of LaNiO
Valerio Olevano, Fabio Bernardini, Xavier Blase +1
We present an ab initio self-energy calculation of the electronic structure of LaNiO. With respect to density-functional theory we find that in the La 4 states und…
Evidence of the isoelectronic character of F doping in SmFeAsO(1-x)F(x): a first-principles investigation
Fabio Bernardini, Federico Caglieris, Ilaria Pallecchi +1
We study the electronic structure of the SmFeAsO(1-x)F(x) alloy by means of first-principle calculations. We find that, contrary to common believe, F-doping does not change the cha…
Unconventional disorder effects in correlated superconductors
Maria N. Gastiasoro, Fabio Bernardini, Brian M. Andersen
The understanding of disorder has profoundly influenced the development of condensed matter physics, explaining such fundamental effects as, for example, the transition from ballis…
The phase diagrams of iron-based superconductors: theory and experiments
A. Martinelli, F. Bernardini, S. Massidda
Phase diagrams play a primary role in the understanding of materials properties. For iron-based superconductors (Fe-SC), the correct definition of their phase diagrams is crucial b…
