33 p, 1.2 MB Water adsorption, dissociation and oxidation on SrTiO3 and ferroelectric surfaces revealed by ambient pressure X-ray photoelectron spectroscopy / Domingo Marimon, Neus (Institut Català de Nanociència i Nanotecnologia) ; Pach, Elzbieta (Institut Català de Nanociència i Nanotecnologia) ; Cordero Edwards, Rohini Kumara (Institut Català de Nanociència i Nanotecnologia) ; Pérez-Dieste, Virginia (ALBA Laboratori de Llum de Sincrotró) ; Escudero, Carlos (ALBA Laboratori de Llum de Sincrotró) ; Verdaguer Prats, Albert (Institut de Ciència de Materials de Barcelona)
Water dissociation on oxides is of great interest because its fundamental aspects are still not well understood and it has implications in many processes, from ferroelectric polarization screening phenomena to surface catalysis and surface chemistry on oxides. [...]

The propagation front of a crack generates large strain gradients and it is therefore a strong source of gradient-induced polarization (flexoelectricity). Herein, we demonstrate that, in piezoelectric materials, a consequence of flexoelectricity is that crack propagation is helped or hindered depending on whether it is parallel or antiparallel to the piezoelectric polar axis. [...]

Polarization dependence of water adsorption and desorption on LiNbO₃ surfaces was demonstrated using X-ray photoelectron spectroscopy (XPS) carried out in situ under near-ambient conditions. Positive and negative (0001) faces (z-cut) of the same crystal were compared for the same temperature and pressure conditions. [...]

22 p, 2.4 MB Ferroelectrics as smart mechanical materials / Cordero Edwards, Rohini Kumara (Institut Català de Nanociència i Nanotecnologia) ; Domingo Marimon, Neus (Institut Català de Nanociència i Nanotecnologia) ; Abdollahi, Amir (Universitat Politècnica de Catalunya. Laboratori de Càlcul Numèric) ; Sort Viñas, Jordi (Universitat Autònoma de Barcelona. Departament de Física) ; Catalan, Gustau (Institut Català de Nanociència i Nanotecnologia)
The mechanical properties of materials are insensitive to space inversion, even when they are crystallographically asymmetric. In practice, this means that turning a piezoelectric crystal upside down or switching the polarization of a ferroelectric should not change its mechanical response. [...]
