Abstract

The possibility of controlling the properties related to polarization in a ferroelectric material by modifying charged domain walls using low power light promises, in the near future, establishment of new paradigms for the development of micro and nanotechnology devices, based on this coupling between light and matter. However, experimental and theoretical studies about this new phenomenology are still scarce. Thus, the proposal of this project is to research the scope of this new concept of coupling between light and matter, exploring both local and macroscopic effects in the electrical and mechanical properties of ferroelectric crystals and polycrystals when an induced reconfiguration of the ferroelectric domain structure by light happens. Subsequently, and based on the experimental results, it is intended to deepen the physical origin through the development of theoretical models that can describe the observed phenomena, thus guaranteeing posteriorly, the convergence of the scientific knowledge in the development of new technological applications.
