Objectives
The objective is the development of new, knowledge-based materials and heterostructures for
applications in information technologies: computer memories, sensors and actuators, and magnetoelectronic and optoelectronic devices. Equally important, the research is aimed at the
improvement of existing fundamental knowledge on the preparation processes and the structure, properties and mechanisms present in these materials. Given their direct impact on
applications, the transfer of this knowledge to industry is contemplated as a general objective.
