ABSTRACT
The obtaining of electroceramic materials in the form of a thin film represents a critical issue for its application in electronic devices since this is the required geometry for the integration of this material in microelectronic circuits. There are several techniques for this purpose, from those that use a gas or plasma phase to transport the precursors to the substrate, which would be included within the PVD or CVD techniques (for its acronym Physical Vapor Deposition and Chemical Vapor Deposition) to those that use a phase liquid for this transport, which would be included under the CSD (Chemical Solution Deposition) techniques. However, among the large number of published papers, there is much controversy about which of them would be most suitable. Nevertheless, there is a common aspect in the specialised literature that seems to be in agreement: the first group of techniques require very sophisticated equipment that involves high energy consumption in terms of temperature and pressure (vacuum), while the techniques that are based on solutions are characterised by their higher simplicity. In this context, the purpose of this seminar is to summarise the main aspects of each technique in the obtaining of electroceramic thin films, from those that are more sophisticated to the simplest and environmentally benevolent ones, in order to provide an easier understanding of them.
ABOUT THE PRESENTER
During his scientific career, Professor Carlos Gumiel Vindel has acquired experience on the synthesis, processing, and characterisation of diverse electroceramic materials with special emphasis in soft processing technologies leading to materials and/or devices with enhanced properties. The most relevant and innovative scientific developments along his scientific career can be summarised from two main points of view: alternative processes for the sustainable preparation of high-quality materials and better understanding of the physical and chemical phenomena involved during the fabrication of functional ceramics. The different projects and publications in top journals support this fact. Also, in the frame of those projects he has acquired a deep knowledge about the interphase phenomena related to the nanostructure development and the functional response of different types of materials, primarily electroceramics. The synthesis of nanostructures from
chemical routes, the functionalisation of particles and/or assemblies, and in particular the preparation of films, coatings, and homogeneous deposits onto selected substrates, are among the skills that have led him to succeed in the achievement of (micro) nanostructured materials and functional nanophases with scientific and industrial interest.
Professor Vindel is currently the Director of the Bachelor’s Degree in Industrial Technologies Engineering and Head of the Department of Chemistry at Nebrija University, Madrid (Spain). He is a member of the Materials and Advanced Manufacturing Research Team. Simultaneously, he maintains a close collaboration with research teams belonging to the Ceramic and Glass Institute of Madrid (Spanish National Research Council), the Materials Institute of Madrid (Spanish National Research Council) and the Industrial Engineering Faculty of the Universidad de Castilla la Mancha, developing research tasks in the field of thin films ceramic materials processed by a sustainable procedure.
