16 p, 719.6 KB Above-Bandgap Photovoltages in Antiferroelectrics / Pérez Tomàs, Amador (Institut Català de Nanociència i Nanotecnologia) ; Lira Cantú, Mónica (Institut Català de Nanociència i Nanotecnologia) ; Catalan, Gustau (Institut Català de Nanociència i Nanotecnologia)
The closed circuit photocurrent and open circuit photovoltage of antiferroelectric thin films were characterized both in their ground (antipolar) state and in their polarized state. A sharp transition happens from near zero to large photovoltages as the polarization is switched on, consistent with the activation of the bulk photovoltaic effect. [...]

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. [...]

129 p, 3.7 MB Flexoelectricity in biomaterials / Vásquez Sancho, Fabián, autor. ; Catalan Bernabé, Gustau, supervisor acadèmic. ; Sort Viñas, Jordi, supervisor acadèmic. ; Universitat Autònoma de Barcelona. Departament de Física. ; Institut Català de Nanociència i Nanotecnologia.
La flexoelectricidad es la capacidad de los materiales para generar electricidad al deformarse de forma no homogénea. Es una propiedad de todos los materiales y, en principio, posible que existiera en biomateriales. [...]
Flexoelectricity is the ability of materials to generate electricity upon being bent, or, more generally, upon being inhomogeneously deformed. It is a property that is allowed by symmetry in all materials and, therefore, it was in principle possible that it existed in biomaterials –one precedent existed for their observation in inner-ear stereocilia, in fact, pointing to its importance for acousto-electric transduction in mammalian hearing.

117 p, 2.0 MB Effect of flexoelectricity on the nano-mechanical properties of ferroelectrics / Kumara Cordero, Edwards, autor. ; Catalan Bernabe, Gustau, supervisor acadèmic. ; Domingo Marimon, Neus, supervisor acadèmic. ; Sort Viñas, Jordi, supervisor acadèmic. ; Universitat Autònoma de Barcelona. Departament de Física. ; Institut Català de Nanociència i Nanotecnologia.
Los materiales ferroeléctricos pueden tener diferentes respuestas electromecánicas, por ejemplo la piezoelectricidad, polarización inducida cuando hay deformación homogénea, y la flexoelectricidad, polarización inducida cuando hay deformación inhomogénea. [...]
Ferroelectric materials can present various electromechanical responses. These include electrostriction (strain proportional to the square of the electric field) piezoelectricity (polarization induced by a strain), and flexoelectricity (polarization induced by a strain gradient). [...]

110 p, 3.0 MB Flexoelectricity in single crystals / Narvaez Morales, Jackeline ; Catalan Bernabé, Gustau, dir. ; Domingo, Neus ; Universitat Autònoma de Barcelona. Departament de Física
En términos generales, la flexoelectricidad es la respuesta de la polarización a un gradiente de deformación. A diferencia del efecto piezoeléctrico, este efecto está presente en todos los materiales independientemente de su estructura cristalina. [...]
In general terms, flexoelectricity is the response of polarization to a strain gradient. In contrast to the piezoelectric effect, this effect is present in all materials regardless of their crystal structure. [...]
