The effect of composition on phonon softening in ABO3-type perovskites: DFT modelling
Autor: Gustavo Sophia, Philippe Baranek, Michel Rérat, Roberto Dovesi
Publikováno v: Physical Chemistry Chemical Physics. 24:27064-27074
The influence of the A cation on the ferroelectric instability in ABO3 perovskites, and its associated F1u IR-active phonon mode, is systematically investigated for tantalates, niobates and titanates at the hybrid density-functional theory level.

New Architecture and Bonding Process for III-V//Si Tandem Solar Cells
Autor: Francois Chancerel, David Lackner, Philippe Baranek, Oliver Höhn, Stéphane Collin, Frank Dimroth, Phuong-Linh Nguyen, Andrea Cattoni, Marco Faustini
Publikováno v: Scopus-Elsevier
We propose an easy and low-cost bonding method for III-V//Si tandem solar cells, based on conductive sol-gel-derived and hybrid materials. The design enables current matching and photon recycling. First prototypes have been demonstrated successfully.

A comment on 'The interaction of X2 (X = F, Cl, and Br) with active sites of graphite' [Xu et al., Chem. Phys. Lett., 418, 413 (2006)]
Autor: Holger Vach, Christoph Lechner, Philippe Baranek
Publikováno v: Chemical Physics Letters. 698:93-96
In their article, Xu et al. (2006) present the adsorption energies for the chemisorption of the three halogens F 2 , Cl 2 , and Br 2 on the active sites of graphite. The three investigated systems are the three most stable surfaces, (0 0 1), (1 0 0),
