Resumo
This project proposes the investigation of dielectric, ferroelectric, piezoelectric and photovoltaic, in addition to phenomenological analyses, in single crystals of (K,Na)NbO3 doped with CuO (KNN-Cu), (K,Na,Li)(Nb,Ta,Sb)O3 (KNN-LTS) and (K,Ba)(Nb,Ni)O3 (KBNN) grown by the vertical Bridgman-Stockbarger method. The growth of the KNN-Cu composition will be carried out based on the experienc…
