Optoeletronic and Ferroeletric Applications

Abstract

In this chapter, some of the tendencies in the fields of nanostructured materials for optoeletronic and ferroelectric applications in terms of research and industry are presented. Special emphasis is given to carbon nanotubes, graphene, perovskite, aurivillius and thin films. In the field of nanotechnology applied to ceramic materials, there are different methods of fabrication and processing of these materials, such as powder form, bulk or thin films. The appropriate choice of processing depends on the application desired. The main tendency for both optoeletronic and ferroelectric applications is the use of thin films, which can contribute to the minituarization of devices such as transistors, photovoltaics, liquid crystals, light emitting diodes and sensors. Different techniques can be used to produce these nanometric structures as thin films, including in-situ growth and post-synthesis techniques. The selection of the adequate technique depends on the material and thickness of the film desired, which will have direct effect over the properties.
