Nanoscience and Nanotechnology have experienced a tremendous growth in few years. Nanotechnologies are the design, characterization, production and application of structures, devices and systems by controlling shape and ...
Este trabajo se enmarca dentro de la modelización óptica y estructural de capas delgadas semiconductoras, particularmente de óxidos conductores transparentes del tipo ZnO y ZnO:Al, así como de capas dopadas tipo p y tipo ...
In 2004 there were newly conditions for a scientific revolution, with very important technology implications and yet to be completely developed. It is the isolation of atomic carbon layers, better known as graphene, whose ...
Esta tesis se centra en el desarrollo de nuevos recubrimientos depositados por técnicas PVD, con propiedades funcionales específicas, diseñados para obtener la competitividad deseada de estos productos en el mercado ...
The concept of nanotechnology is attributed to Nobel prize winner Richard Feynman who gave a very famous, visionary in 1959 (published in 1960) during one of his lectures, saying: "the principles of physic, as far as I can ...
The objective of this work was to study two different light management approaches to enhance the efficiency of thin film Si solar cells and these were the manipulation of the light path (light trapping) and changing the ...
La introducció dels feixos amb polaritzacions no uniformes ha aportat grans avenços en multitud d'àrees. En un nivell més fonamental, ha permès entendre la naturalesa de la llum d'una manera més amplia, estenent les teories ...
La solució sòlida BaZrxTi1-xO3 (BZT) presenta un ampli ventall de propietats dielèctriques que la fan interessant tant des del punt de vista fonamental com d'aplicacions. Els estudis del BZT en forma màssica han mostrat ...
Plasma Polymerization is a novel technique for the preparation of polymer-like thin film coatings at low temperatures onto almost any type of substrates: plastic, metal, semiconductors, wood, textile fibers or membranes, ...
Multiferroic materials, in which two or more ferroic ordering take place in the same phase, have driven major interest in the last few years, not only due to the possibility of exploring novel physical properties in those ...
