Resumen:
<!-- @page { margin: 2cm } P { margin-bottom: 0.21cm } --> Ab-initio and atomistic simulations are presented on ferroelectric perovskites and Hydrogen bonded ferroelectrics. Concerning the perovskites, results are shown for simple as well as layered perovskites and relaxor materials. Calculations have been performed for bulks, thin films, superlattices and nanoparticles. In the area of H-bonded ferroelectrics, the origin of the ferroelectric or antiferroelectric transition has been investigated in KDP (KH2PO4) and ADP (NH4H2PO4).
