19 p, 644.7 KB Translational covariance of flexoelectricity at ferroelectric domain walls / Diéguez, Oswaldo (Institut Català de Nanociència i Nanotecnologia) ; Stengel, Massimiliano (Institut de Ciència de Materials de Barcelona)
Macroscopic descriptions of ferroelectrics have an obvious appeal in terms of efficiency and physical intuition. Their predictive power, however, has often been thwarted by the lack of a systematic procedure to extract the relevant materials parameters from the microscopics. [...]

Using scanning probe microscopy, we measure the out-of-plane mechanical response of ferroelectric 180° domain walls and observe that, despite separating domains that are mechanically identical, the walls appear mechanically distinct-softer-compared to the domains. [...]

ABINIT is probably the first electronic-structure package to have been released under an open-source license about 20 years ago. It implements density functional theory, density-functional perturbation theory (DFPT), many-body perturbation theory (GW approximation and Bethe-Salpeter equation), and more specific or advanced formalisms, such as dynamical mean-field theory (DMFT) and the "temperature-dependent effective potential" approach for anharmonic effects.

Harvesting environmental energy to generate electricity is a key scientific and technological endeavour of our time. Photovoltaic conversion and electromechanical transduction are two common energy-harvesting mechanisms based on, respectively, semiconducting junctions and piezoelectric insulators. [...]

One of the main strategies to control magnetism by voltage is the use of magnetostrictive-piezoelectric hybrid materials, such as ferromagnetic-ferroelectric heterostructures. When such heterostructures are subjected to an electric field, piezostrain-mediated effects, electronic charging, and voltage-driven oxygen migration (magnetoionics) may simultaneously occur, making the interpretation of the magnetoelectric effects not straightforward and often leading to misconceptions.

170 p, 1.9 MB First-principles theory of flexoelectricity : methods and applications / Schiaffino, Andrea Maria Enrico ; Stengel, Massimiliano, dir. ; Sánchez Moreno, Álvaro, dir. ; Universitat Autònoma de Barcelona. Departament de Física
Esta tesis se centra en los desarrollos recientes de la teoría microscopía de la exoelectricidad y sus aplicaciones prácticas con tal de estudiar la respuesta física en sistemas concretos. La exoelectricidad es la propiedad electromecánica de todos los aislantes de desarrollar una respuesta polar a una perturbación uniforme del gradiente de deformación. [...]
