Photo-Stimulated Nanopattern Formation Dynamics on Ferroelectric Surfaces

Project: Research project

Description

Ferroelectric materials are in the class of pyroelectric materials with a spontaneous polarization that can be switched through the application of an external electric field. The spontaneous polarization of ferroelectric materials is characterized by a polarization bound charge that develops due to the discontinuity of the polarization at the surface. The polarization bound charge for many ferroelectric materials can lead to significant electric fields near the materials surface, and this field can be employed in electronic applications such as ferroelectric random access memory. The combination of configurable submicron ferroelectric domains, the electric field near the surface, and the variations induced by above band gap illumination can drive new approaches to nanopatterning which is the focus of this project.
